To remove someone from your friends list on a social networking site把某人從社群網站的好友名單上移除, so that you are no longer connected there讓你們在那裡不再是連結的關係。It is a verb這是個動詞: you unfriend someone你unfriend某人。Facebook is where the word grew up這個字是從Facebook發跡的, and it is still the platform people mean by default大家講到這個字，預設指的還是Facebook; on other apps the word is usually 'unfollow' or 'block'在其他app上，通常會用『unfollow』或『block』, which are different things這是不同的事。

The differences matter socially. Unfriending cuts the connection completely and is often a real statement — you are done with this person, or at least done seeing them. Unfollowing quietly hides their posts while you stay connected, so it is the polite, invisible option. Blocking is the strongest: they cannot even find you. So when someone says 'she unfriended me', there is usually a story behind it, and often hurt feelings.

The word is worth noticing as a piece of living English. It got common around 2008-2010 and was a word-of-the-year pick, and its shape is unusual: English normally puts un- on adjectives and on verbs meaning 'undo an action' (untie, unlock), but here it was stuck onto a noun, 'friend', to make a brand-new verb. There was also an old, unrelated noun 'unfriend' meaning an enemy, but nobody uses that today.

The word is worth noticing as a piece of living English這個字值得注意，因為它是英文活生生演變的一個例子。It got common around 2008-2010它大約在2008到2010年變得普遍 and was a word-of-the-year pick還曾被選為年度風雲字, and its shape is unusual而且它的構詞方式很特別: English normally puts un- on adjectives and on verbs meaning 'undo an action' (untie, unlock)英文通常把un-加在形容詞上，或加在表示『撤銷動作』的動詞上（像untie、unlock）, but here it was stuck onto a noun, 'friend', to make a brand-new verb但這裡卻是加在名詞『friend』上，造出一個全新的動詞。There was also an old, unrelated noun 'unfriend' meaning an enemy以前也有個不相關的舊名詞『unfriend』，意思是敵人, but nobody uses that today但現在沒有人這樣用了。
