An oxide is a substance produced when something combines with oxygen. Rust is mostly iron oxide.

Carbon dioxide, the gas we breathe out, is an oxide of carbon — though actually learners are often surprised by that, because “oxide” sounds like a solid powder, not a gas. Water can be described as hydrogen oxide, but nobody says that at the dinner table.

Carbon dioxide, the gas we breathe out二氧化碳，也就是我們呼出來的那種氣體, is an oxide of carbon是carbon（碳）的一種oxide — though actually learners are often surprised by that不過其實學習者常常對這件事感到驚訝, because 'oxide' sounds like a solid powder, not a gas因為「oxide」聽起來像是固體粉末，不像氣體。Water can be described as hydrogen oxide水可以被稱為hydrogen oxide（氧化氫）, but nobody says that at the dinner table但沒有人會在餐桌上這樣講。

The word belongs to science class: you meet it in names like calcium oxide or iron oxide.

The word belongs to science class這個字屬於科學課: you meet it in names like calcium oxide or iron oxide你會在calcium oxide（氧化鈣）或iron oxide（氧化鐵）這類名稱裡遇到它。

An oxide is not oxygen itself (oxygen is the gas that joins in). It is also not the process; that process is oxidation.

An oxide is not oxygen itselfoxide不是氧本身 (oxygen is the gas that joins in)（氧是那個加進去的氣體）。It is also not the process它也不是那個過程; that process is oxidation那個過程叫做oxidation（氧化）。

The French made the word by blending ox(ygene) and (ac)ide, so the pieces point to oxygen and acid, but in English today oxide just names this kind of compound.

The French made the word by blending ox(ygene) and (ac)ide法文把這個字拼成是ox(ygène)和(ac)ide兩個字融合出來的, so the pieces point to oxygen and acid所以這些字塊指向氧和酸, but in English today oxide just names this kind of compound但在今天的英文裡，oxide就只是這一類化合物的名稱。
