Stoical describes someone who keeps calm and does not complain while something painful or unpleasant is happening to them, or describes the behaviour itself: a stoical patient, a stoical silence, stoical about losing the money. It is an adjective only — the person is a stoic, and what they are is stoical. English also allows stoic as an adjective with the same meaning, and the two are interchangeable in almost every sentence; stoical feels slightly more literary and is a little more common in British writing, while American writers reach for stoic. The word is somewhat formal and belongs more to writing than to daily talk — at a hospital bed people say 'she's being very brave' far more often than 'she's being very stoical'. As with stoic, the word describes the outside, not the inside: it says nothing about whether the person is suffering, only that they are not showing it, and it is often used with a touch of concern for exactly that reason.

堅忍的、逆來順受的、不抱怨的。書面語氣，日常口語更常說 brave。「逆來順受」帶點被動接受的意味，stoical 則偏重「忍住不表現出來」。
