te-form for adverbial chaining

A te-form verb used adverbially to modify the manner or means of the next verb — 'doing X-ly,' '[in manner X], [main action Y],' or 'by doing X, Y.' Examples: 自信を持って答える ('answer with confidence'), 急いで走る ('run in a hurry'), 急いで食べた ('ate in a hurry'), 雨に濡れて帰った ('came back soaking wet'). Distinct from sequential te-form chains (X then Y) and causal te-form (X so Y); the focus rests on the manner of the second verb.
