What does did mean?
"Did" is the simple past tense of the highly irregular English verb "do", meaning to perform, carry out, or complete an action. It serves two central grammatical roles. As a main verb, it describes an action performed at a specific time in the past: "She did her chores before breakfast." As an auxiliary or helping verb, it is essential to forming questions, negatives, and emphatic statements about the past — as in "Did you enjoy it?", "We didn't notice", and "I did tell you so" — always followed by the base form of another verb. Because "do" is among the most frequently used verbs in English, "did" appears constantly in both speech and writing, across all registers from casual conversation to formal prose. Its roots stretch back to Old English "dyde", itself descended from ancient Germanic origins, making it one of the oldest verbs in the language. Mastering its correct use with infinitives, rather than past-tense forms, is a hallmark of standard English grammar.

Etymology of did
The word "did" descends directly from Old English "dyde", the past tense of "dōn" (to do). The underlying root is Proto-Germanic *dōną, which in turn traces back to the Proto-Indo-European root *dheh₁-, meaning "to put" or "to set". This same Indo-European root gave rise to Latin "facere" (to make), producing English words like "fact" and "factory", as well as Greek "tithēmi" (to place). Cognates include German "tat" (deed) and Dutch "daad". The verb's irregular past form has been stable for well over a thousand years, making "did" one of the most enduring words in the English language.
How did is actually used
In standard English, "did" must be followed by the bare infinitive of another verb when acting as an auxiliary ("Did he go?", not "Did he went?"). In some non-standard dialects, "done" appears where "did" is expected; this is considered informal or regional.
Easily confused with did
"Did" is the simple past form of "do" (e.g. "she did it yesterday"), while "done" is the past participle used with have/has/had (e.g. "she has done it") and never stands alone as a finite verb in standard English.
