Training is the correct spelling. Trainning is a misspelling and should not be used in standard English. The word training is formed from the verb train by adding the suffix -ing: train + ing = training. You do not add another n. Training can refer to learning skills, preparing for a sport or activity, or developing knowledge for a job or task.
Quick Answer
Training is the correct spelling, while trainning is incorrect in standard English. The word comes from train + -ing, so the final n in train is not doubled. Use training in sentences such as “I have training tomorrow” and “The company provides employee training.” If you see trainning, correct it to training. The spelling is the same in American and British English.
What Is Training?
Training is the correct -ing form of the verb train, and it is also a noun. As a verb form, training describes the action of teaching, practicing, or preparing someone or something. As a noun, it commonly means the process of learning skills or knowledge needed for a job, activity, sport, or other purpose.
For example, a new employee may receive training before starting a job, while an athlete may be training for a competition. The word is also widely used in education, business, technology, fitness, and professional development. Dictionary references list training as the standard form.
The spelling trainning does not represent a different English word. It is simply an incorrect spelling of training.
Why It Matters
Spelling training correctly matters because the word appears frequently in professional, academic, and everyday English. You may use it in a résumé, job application, employee handbook, school assignment, email, training plan, or social media post.
A spelling mistake can make otherwise clear writing look less polished. This is especially noticeable in professional contexts. For example, a heading such as “Employee Trainning Program” contains an unnecessary n and should be written as “Employee Training Program.”
The mistake is also easy to repeat because the pronunciation does not clearly tell you whether the written word contains one n or two. Learning how the word is formed is therefore more useful than relying only on how it sounds.
The Core Rule
The correct spelling is training: train + ing = training.
Do not double the final n when adding -ing to train.
Correct: training
Incorrect: trainning
The important point is that English does not automatically double every final consonant before -ing. Consonant-doubling rules depend on the spelling and pronunciation pattern of the base word. Train does not meet the conditions that would require the final n to be doubled.
How to Use Training Correctly
Training as a noun
As a noun, training usually refers to the process of gaining skills, knowledge, or preparation. It can be used for professional development, sports, education, practical skills, or many other activities.
- She received training before starting the new job.
- The company provides safety training for all employees.
- He needs more training in computer programming.
- The athlete is in training for the competition.
- Our team completed customer service training.
In standard usage, training is generally treated as an uncountable noun when it refers to training as a general activity or process. For example, “The staff need more training” is natural English. When you need to count individual events, use expressions such as training sessions or training courses.
Training as a verb form
Training can also be the present participle or gerund form of train. In a progressive verb construction, it describes an action that is happening or was happening around a particular time.
- I am training for a marathon.
- She is training the new employees.
- They were training at the gym yesterday.
- We are training our staff to use the new software.
Here, training is connected directly to the verb train. The same spelling is used whether the word functions as part of a verb phrase or as a noun.

| ❌ Incorrect | ✅ Correct | Why |

| Employee trainning starts Monday. | Employee training starts Monday. | The extra n should be removed. |
| He completed his trainning. | He completed his training. | Training is the standard noun form. |

Why People Make This Mistake
Phonetic similarity
The pronunciation of training does not make the spelling distinction obvious. When people hear the word rather than see it, they may imagine that the consonant sound should be represented by two written ns. English spelling does not always work that way.

Confusion about doubled consonants
English has many words in which a final consonant is doubled when a suffix is added. This can encourage learners to apply the pattern too broadly. For example, run becomes running, and sit becomes sitting. However, train does not follow that pattern. It becomes training.
Spelling overlap
The word train already ends in n, and the suffix -ing begins with a vowel. When the two parts are joined, the result is simply training. There is no second n between them.
Autocomplete and spellcheck
Typing quickly can produce trainning, especially when the writer is thinking about the pronunciation rather than the spelling. Spellcheck tools can often identify such errors, but automated checking should not replace knowledge of common word forms. A spellchecker may miss a mistake in some contexts or may not explain why the spelling is wrong.
Translation interference
English learners who use another language as a reference may transfer spelling patterns from that language. A learner may also memorize a spoken English word without seeing it written frequently. The safest approach is to remember the English word as a complete spelling: training.
Common Mistakes Checklist
Adding an extra n
Mistake: Writing trainning.
Why it happens: The writer assumes the final consonant should be doubled.
How to avoid it: Remember the simple formation train + ing = training.
Thinking trainning is an alternative spelling
Mistake: Treating trainning as a regional or alternative version of training.
Why it happens: Some English words have different American and British spellings.
How to avoid it: Do not apply regional spelling differences here. Training is the standard spelling in both varieties.
Confusing spelling with pronunciation
Mistake: Trying to determine the number of letters from the sound alone.
Why it happens: English pronunciation does not always provide a one-to-one guide to spelling.
How to avoid it: Learn the written form separately: training.
Using “a training” automatically
Mistake: “I attended a training yesterday.”
Why it happens: Learners may treat training as a countable event in the same way as class or meeting.
How to avoid it: In standard usage, use a training session, a training course, or simply training, depending on the meaning. Cambridge specifically notes that training does not normally have a plural form and recommends phrases such as training session or training course when referring to an individual event.

Training in Real English
Grammatically correct and natural: “I need more training.”
This is natural everyday English when someone means they need additional instruction or practice. Training is being used as an uncountable noun, so there is no need for an article before it. The sentence works in workplace, educational, technical, and personal-development contexts. It is concise and sounds natural because English commonly treats training as a general process rather than as a collection of individual events.
Grammatically correct and natural: “She is training for the competition.”
This sentence uses training as part of the present progressive verb phrase is training. It means she is currently preparing through exercise or practice. The same construction works with sports, professional skills, physical activities, and other forms of preparation. For example, “He is training for the interview” can be understood in a preparation context, while “She is training for the race” is a common sports-related use.
Grammatically possible but less natural: “I attended a training.”
Some speakers, particularly in workplace contexts influenced by business English used internationally, may use a training to mean one training event. However, this is not the most natural general-English choice. I attended a training session, I attended a training course, or I attended training is clearer depending on the intended meaning. Cambridge advises using a phrase such as training session or training course for a singular event.
Incorrect: “The company provides several trainnings.”
The spelling is incorrect, and the plural form is also usually unsuitable when training means the general process of teaching skills. The normal expression is “The company provides training.” If you mean several separate events, say “The company provides several training sessions” or “The company offers several training courses.” This separates the spelling issue from the countability issue and makes the sentence more precise.
American vs. British English
There is no meaningful American-versus-British spelling difference between training and trainning. Training is the standard spelling in both varieties of English. Dictionary sources give the same spelling and pronunciation for American and British English.
Therefore, changing from American English to British English does not make trainning acceptable. If you are writing for an American, British, or international audience, use training.
Formal vs. Informal Usage
The spelling training is appropriate in both formal and informal writing. You can use it in a casual text message, a professional email, an academic paper, a résumé, or a company policy.
The main register issue concerns phrases surrounding the word rather than the spelling itself. For example, “I need some training” works in ordinary conversation, while “Employees must complete mandatory safety training before operating the equipment” is suitable for formal workplace writing.

How to Remember the Correct Spelling
The easiest memory trick is to build the word from its base form:
TRAIN + ING = TRAINING
Look at the boundary between the two parts:
train | ing → training
There is already one n at the end of train. The suffix -ing does not add another n.
You can also remember this short sentence:
“Train once, then add ing.”
Do not insert another n between train and ing.
Real-Life Situations
Job interview
Correct: “I completed customer-service training before applying for this position.”
This works because training describes the instruction or preparation the applicant received.
Work meeting
Correct: “The new employee training will begin next week.”
Here, training functions as part of a compound noun referring to instruction for new employees.
Professional email
Correct: “Please confirm your attendance at the training session.”
Training session is useful when you mean one specific event rather than training as a general process.
Text message
Correct: “I’m heading to training now.”
This informal sentence is completely natural when the context makes the type of training clear.
Exam or academic assignment
Correct: “Professional training can improve employees’ technical skills.”
The spelling remains training regardless of whether the sentence is formal or informal.
Other Correct Forms of Train
Understanding the other forms of train can make the spelling of training easier to remember.
| Form | Example |
|---|---|
| train | I train every morning. |
| trains | She trains new employees. |
| trained | He trained for six months. |
| training | He is training for the competition. |
The -ing form is training, not trainning. The past-tense form is trained, and the third-person singular form is trains.
Why Doesn’t Train Become Trainning?
English has rules for doubling a final consonant before certain suffixes, but those rules do not apply to every word ending in a consonant. Words such as run → running and sit → sitting follow a doubling pattern because of their spelling and pronunciation structure.
Train does not need this change. When -ing is added, its spelling remains intact: train + ing = training.
This is why trying to memorize a broad rule such as “double the final consonant before -ing” can create errors. The correct approach is to learn when the doubling pattern applies and when it does not.
Does Training Have a Plural Form?
When training means the general process of learning or preparation, it is normally an uncountable noun. Standard usage therefore does not usually form its plural as trainings. For example, write “Employees need more training,” not “Employees need more trainings.”
When you need to refer to separate events, use a countable noun such as sessions, courses, or programs:
- three training sessions
- two training courses
- several training programs
This is a separate issue from training versus trainning, but it is useful because both mistakes can occur in workplace writing.
