Atypical meansatypical 的意思是 not typical「不典型」：not the usual kind不是常見的那種，not the pattern you expect不是你預期的模式。A typical Monday典型的星期一 is ordinary很平常；an atypical Monday不典型的星期一 has something odd in it有點怪怪的。The word is a little formal這個字有點正式。

Doctors use it a lot: atypical signs do not match the usual picture of an illness. In everyday talk, unusual, not typical, or a bit different often do the same job, and they sound warmer.

Doctors use it a lot醫生很常用這個字：atypical signsatypical 的徵狀 do not match跟...對不上 the usual picture of an illness一般疾病的典型表現。In everyday talk在日常對話裡，unusual, not typical, or a bit differentunusual、not typical，或 a bit different often do the same job常常能達到一樣的效果，and they sound warmer聽起來也比較溫暖。

Though actually, unusual is a bit wider. Unusual just means 'not common'. Atypical quietly points at a pattern first, then steps outside it.

Though actually不過其實，unusual is a bit widerunusual 的範圍比較廣一點。Unusual just meansunusual 就只是 'not common'「不常見」的意思。Atypical quietly points at a pattern firstatypical 則是先悄悄指出一個模式，then steps outside it然後再說這次跳出了那個模式。

Calling a person atypical can sound like a file note — cold, as if they were a sample — so be gentle there. Scientists and teachers also use it for results that do not follow the common pattern.
