also: だ
auxiliary verb
Used in casual speech to make a mild imperative or request. Often has a softening effect compared to the plain imperative form.
て is the connective form linking clauses or actions, whereas た marks past tense or completion, so learners often confuse which suffix to attach to a verb stem.
Standard hiragana spelling for the past/completion auxiliary.
Voiced variant used after certain verb forms (e.g., 読んだ, 飛んだ).
Derived from the classical auxiliary たり, which indicated completion. The modern form た is a contraction used since the Muromachi period.
