A trimmer is a machine or tool for cutting things down to a neat, even shape. The most common ones are a hedge trimmer (for the flat sides and top of a garden hedge) and a lawn trimmer (for grass along walls and fences, where a mower cannot reach). Most trimmers today are electric and use a spinning blade or a fast-moving line, but the word also covers the small hand tools your barber uses on your neck, and the little machines people buy for nose hair, beard, or a pet's fur.

The key idea is not 'cut it off' but 'cut the edges so it looks tidy' — a trimmer takes a little bit from the outside, again and again. Because of this, an English speaker will happily invent 'a ___ trimmer' on the spot for any tidying tool, and other people will understand.

The key idea is not關鍵概念不是 'cut it off''整個剪掉' but而是 'cut the edges so it looks tidy''修邊修到看起來整齊' — a trimmer takes a little bit from the outsidetrimmer是從外側修掉一點點, again and again一次又一次地。Because of this也因為這樣，an English speaker英文母語者 will happily invent 'a ___ trimmer' on the spot會很自然地當場自創「一個___ trimmer」 for any tidying tool來講任何整理用的工具, and而 other people will understand其他人也聽得懂。

Note the word can also mean a person: someone whose job is to trim (a hedge trimmer can be a worker as well as a machine), and in older, more bookish English, a trimmer is a person who has no real opinion and simply agrees with whoever is winning. That last sense comes from sailing — you 'trim' the sails to match the wind — and you will meet it in writing about politics more than in speech.

Note注意 the word can also mean a person這個字也可以指人：someone whose job is to trim指工作是修剪的人 (a hedge trimmer can be a worker as well as a machine)（hedge trimmer既可以是工人，也可以是機器）, and而 in older, more bookish English在比較老派、書面的英文裡, a trimmer is a persona trimmer指的是一種人 who has no real opinion and simply agrees with whoever is winning沒有真正立場、只會附和贏的一方的。That last sense comes from sailing最後這個意思來自航海——you 'trim' the sails to match the wind你會'trim'船帆去配合風向——and而 you will meet it in writing about politics你比較會在講政治的文章裡遇到這個用法 more than in speech而不是在口語裡。
