A parenthetical remark is something you drop in while you are already talking or writing about something else — a little extra that explains, names, or adds a side thought.

A parenthetical remark插入的話 is something you drop in是你在講或寫別的事情時順帶加進去的東西 while you are already talking or writing about something else，— a little extra一個小小的附加內容 that explains, names, or adds a side thought用來解釋、指名，或加上一個旁支的想法。

In writing it often sits inside brackets ( ), or between dashes or commas. In speech it sounds like a quick aside you could lift out without breaking the main sentence.

In writing在書面上 it often sits inside brackets ( )它常常放在括號（）裡面，or between dashes or commas或是放在破折號或逗號之間。In speech在口語裡 it sounds like a quick aside它聽起來像一句可以拿掉的插話 you could lift out without breaking the main sentence拿掉也不會破壞主句。

Though actually, people also use parenthetical as a noun for that extra bit itself: “just a parenthetical.” It is a school-and-writing word; in casual talk people say “by the way” or “just to add.” The spelling looks as if it had to do with mums and dads.

Though actually不過其實，people also use parenthetical as a noun for that extra bit itself人們也會把parenthetical當名詞來指那個附加的部分本身："just a parenthetical."「just a parenthetical.」It is a school-and-writing word這是個學校和寫作場合用的詞；in casual talk在日常對話裡 people say "by the way" or "just to add."人們會說「by the way」或「just to add」。The spelling這個拼法 looks as if it had to do with mums and dads看起來好像跟爸爸媽媽（parent）有關。

It does not. It belongs with parenthesis — the brackets — from Greek for placing something in beside the main thing.

It does not其實沒有關係。It belongs with parenthesis它跟parenthesis（括號）是一家的 — the brackets也就是括號本身 — from Greek源自希臘文 for placing something in beside the main thing意思是把某個東西放在主要事物的旁邊。
