Always use the correct past tense form "did not extend" instead of "did not extended". The auxiliary verb 'did' already indicates past tense, so the main verb 'extend' should be in its base form.
Common error

The phrase "did not extended" is a grammatically incorrect construction. The correct form is "did not extend". As Ludwig AI explains, using "extended" (past participle) after the auxiliary verb "did" is a common mistake. The auxiliary verb "did" already indicates past tense. While examples exist, they highlight the error rather than proper usage. Always use the base form of the verb after "did not" to ensure grammatical correctness. Consider using alternatives like "did not prolong" or "did not lengthen" to clearly convey your intended meaning.
