Don’t Forget vs. Don’t Forgot – Which is Correct?
“Don’t forget” is the correct phrase in standard English. “Don’t forgot” is incorrect because the auxiliary verb “do” requires the base form “forget,” not the past-tense form “forgot.” Use “don’t forget” for reminders, instructions, and advice, whether speaking casually or writing in a professional context, clearly and confidently.
Don’t Forget or Don’t Forgot – Which Is Correct?
“Don’t forget” is correct, while “don’t forgot” is a grammatical error. The word “don’t” is a contraction of “do not.” When do or does is used as an auxiliary verb, the main verb must remain in its base form.
Therefore, the correct structure is do not forget, not do not forgot. The word forgot is the simple past tense of forget, so it cannot normally follow don’t.
Use “Don’t forget” when giving a reminder, warning, instruction, or piece of advice. For example, you can say, “Don’t forget your umbrella.” You can use “forgot” in a sentence such as, “I forgot my umbrella,” where no auxiliary verb requires the base form.
The Best Trick to Remember the Difference
Use the do-support test: whenever you see do, does, or did before a verb, use the verb’s base form.
Remember this pattern:
- Do not forget — correct
- Does not forget — correct
- Did not forget — correct
- I forgot — correct without an auxiliary verb
A simple mnemonic is: “Do takes the dictionary form.” Since forget is the dictionary form, it must follow don’t. The past form forgot stands alone, as in “She forgot.”

How to Use Don’t Forget

The phrase can sound friendly and casual, as in “Don’t forget to call me.” It can also be polite and professional when combined with words such as please: “Please don’t forget to attach the document.” In some contexts, the phrase may sound firm, so the surrounding wording and tone are important.

Etymology of the Word Forget
The verb forget comes from Old English forgietan, meaning to lose from memory or fail to remember. It combines an older prefix related to “away” or “completely” with a verb meaning to grasp or retain. Over time, its meaning developed into the modern sense of failing to remember something.
The phrase don’t forget combines the contraction don’t, meaning “do not,” with the base verb forget. Its grammatical structure has remained straightforward: the auxiliary verb carries the negative meaning, while the main verb stays in its base form.
