An eater is a person (or sometimes an animal) looked at through how they eat. We almost never say “an eater” alone; we add a word in front: a big eater eats a lot, a small eater or light eater eats little, a picky eater will only eat certain things, a meat-eater eats meat.

An eater is a person (or sometimes an animal) looked at through how they eat eater 是指從一個人（有時是動物）吃東西的樣子來看待他。 We almost never say "an eater" alone我們幾乎不會單獨說 "an eater"; we add a word in front而是會在前面加個字: a big eater eats a lot'a big eater'（很能吃的人）吃很多, a small eater or light eater eats little'a small eater' 或 'light eater'（吃很少的人）吃得少, a picky eater will only eat certain things'a picky eater'（挑食的人）只吃某些東西, a meat-eater eats meat'a meat-eater'（吃肉的人／肉食動物）吃肉。

So the word is a label for a habit, not a job. It is eat + -er, the “person who does this” ending, going back to Old English etere.

So因此 the word is a label for a habit這個字標記的是一種習慣, not a job而不是職業。 It is eat + -er它是 eat 加上 -er, the "person who does this" ending也就是「做這件事的人」的字尾, going back to Old English etere源自古英文的 etere。

You will hear it in family talk (“She’s a really picky eater”) and in compounds like plant-eater. Though actually, calling someone “a big eater” is usually fond or factual, not rude — unless the tone is unkind.

You will hear it in family talk你會在家人聊天時聽到 ("She's a really picky eater")（「她真的很挑食」） and和 in compounds like plant-eater用在複合字裡，像 plant-eater（草食動物）。 Though actually不過事實上, calling someone "a big eater"叫某人 "a big eater" is usually fond or factual通常是親暱或就事論事, not rude不是無禮 — unless the tone is unkind除非語氣不友善。
