A grandmother's ring, a photograph with no copy, a language with no speakers left, a colleague everyone relied on: all irreplaceable. It is used of people as easily as of things, and about people it is warm praise — 'she's irreplaceable' means the team could hire someone else but never get her back.

A grandmother's ring,一枚祖母的戒指、 a photograph with no copy,一張沒有副本的照片、 a language with no speakers left,一種再也沒有人在說的語言、 a colleague everyone relied on:一位大家都依賴的同事： all irreplaceable.全都是irreplaceable無可取代的。It is used of people as easily as of things,這個字用在人身上和用在東西上一樣容易， and about people it is warm praise而且用在人身上時是一種溫暖的讚美 — 'she's irreplaceable''she's irreplaceable'她是無可取代的 means the team could hire someone else意思是團隊可以另外請人 but never get her back.但永遠找不回她這個人。

It is a common word, fine in speech and writing, and slightly emotional; it usually carries either love or regret. Worth noticing: people sometimes say 'nobody is irreplaceable' as a hard-headed saying about work, which shows the word is really about how we value something, not about the facts of supply.
