In the world of written and spoken communication, English can sometimes feel like a labyrinth of confusing rules, spelling anomalies, and homophones that challenge even the most seasoned writers and speakers. Among the many commonly confused terms, one that frequently trips up both native and non-native English speakers alike is the distinction between “training” and “trainning.” This confusion often arises from the similarity in pronunciation and spelling, but understanding the difference between the two is crucial, especially if you want to maintain accuracy in your writing and communication.
Why Are These Terms Often Confused?
Every day, countless professionals and students find themselves hesitating over how to spell training correctly. Whether writing a resume, preparing a business document, or crafting an email, this seemingly simple word can cause unexpected uncertainty. The good news? There’s a clear and simple answer to the “trainning or training” dilemma: “Training” is the correct spelling, while “trainning” is incorrect.
Definitions and Usage

Let’s address the main question right away: “How do you spell training?” The correct spelling is:
- ✓ Training (correct)
- ✗ Trainning (incorrect)
Training
Training is the correct spelling of the word used to refer to the process of teaching or learning a particular skill, behavior, or task. It can also refer to the systematic development of skills or knowledge, often through practice or instruction. It is used in many contexts, including education, sports, professional development, and more.
Examples of “training” in sentences:
- She is undergoing training to become a certified nurse.
- The company provides ongoing training for its employees.
- The athletes participated in an intense training session to prepare for the competition.
Here, “training” refers to the structured activity designed to teach or improve a specific ability or knowledge.
The Grammar Behind Training
To understand why “training” is correct and “trainning” is incorrect, let’s examine the grammatical rules:
The Rule for Adding -ing to Words Ending in Consonants

When adding -ing to a base word:
- For single-syllable words ending in consonant-vowel-consonant (CVC), double the final consonant
- Example: run → running
- For words ending in consonant combinations or long vowel sounds, do NOT double the final consonant
- Example: train → training
“Train” contains a long vowel sound (ai), so it doesn’t require doubling the ‘n’ when adding -ing.
Trainning
On the other hand, trainning is an incorrect spelling of the word training. Despite how it might sound or look to some, “trainning” is not accepted in modern English usage. The double “n” in this case is a mistake, often arising from confusion over English spelling rules or typographical errors.
Examples of incorrect usage of “trainning”:
- She is undergoing trainning to become a certified nurse.
- The company provides ongoing trainning for its employees.
In these examples, “trainning” is used incorrectly. The correct form should be “training.”
Impact of Incorrect Spelling
Using “trainning” instead of “training” can have several negative consequences:
- Professional Impact
- Reduced credibility in business communications
- Negative impression on potential employers
- Decreased effectiveness of professional documents
- Communication Clarity
- Potential confusion in important messages
- Reduced readability of documents
- Distraction from main message
Comparison Table: Training vs Trainning

To help clarify the differences further, here’s a comparison table that summarizes the key aspects of both terms.
Aspect | Training | Trainning |
---|---|---|
Definition | The process of teaching or learning a skill or task. | Incorrect spelling of “training.” |
Spelling | Correct spelling of the word. | Incorrect, has an extra “n.” |
Grammatical Role | Noun or adjective (e.g., “training session”). | N/A (not recognized as a valid word). |
Common Usage | Used widely in education, work, sports, and development. | Rarely used (incorrect form). |
Pronunciation | Pronounced as /ˈtreɪnɪŋ/ | Same pronunciation but still incorrect in writing. |
Example | “She is attending training to improve her skills.” | “She is attending trainning to improve her skills.” (Incorrect). |
As shown, “training” is the only valid term, while “trainning” should be avoided. The confusion often arises because both words sound the same when spoken aloud, but only one is the proper spelling.
