The adverb of 'tedious': in a way that drags on and bores you. It works in three places. Before an adjective, it is a complaint dressed as a measurement — 'tediously long', 'tediously slow', 'tediously familiar' — telling you both that there is a lot of the thing and that the speaker is fed up with it. With a verb, it describes how something is done or how it proceeds: 'The meeting dragged tediously on.' And in the useful pair 'tediously but necessarily' or 'slowly and tediously', it admits the work was dull while defending it as worth doing. It is a formal, written-feeling word — you find it in reviews, essays, and reports far more than in conversation, where people simply say 'so slow' or 'it went on forever'. A small point worth knowing: writers often use it as gentle self-mockery about their own careful work ('I checked each line tediously'), where it means painstaking as much as boring.

冗長乏味地、繁瑣地；多半用在「tediously long 長得要命」這種抱怨句裡
