Libido is someone’s desire to have sex — the drive itself, not a person and not a describing word. Doctors and psychologists use it.

Libido性慾 is someone’s desire to have sex是一個人想要做愛的慾望 —— the drive itself是那股驅力本身, not a person and not a describing word不是指一個人，也不是形容詞. Doctors and psychologists醫生和心理學家 use it會用這個字.

Freud made it famous, and in his writing it sometimes meant a wider life energy, not only sex. Though actually, when ordinary people say libido now, they almost always mean sex drive: a high libido, a low libido, her libido came back after she rested.

Freud佛洛伊德 made it famous讓這個字變得有名, and in his writing而在他的著作裡 it它 sometimes meant a wider life energy有時候指的是更廣義的生命能量, not only sex不只是性. Though actually不過事實上, when ordinary people say libido now現在一般人說libido的時候, they他們 almost always mean sex drive幾乎都是指性慾: a high libido像high libido性慾很強, a low libido low libido性慾低, her libido came back after she rested她休息之後libido又回來了.

It is a somewhat formal, doctor’s-office word. Friends might say sex drive instead. You do not usually count it (not “three libidos”), but you will hear a high libido or a low libido.

It它 is a somewhat formal, doctor’s-office word是一個有點正式、比較像診間會用的字. Friends朋友之間 might say sex drive instead可能會改說sex drive就好. You你 do not usually count it通常不會拿來數數量, not “three libidos”不會說three libidos, but你 will hear a high libido or a low libido但會聽到a high libido或a low libido這種說法.

It was borrowed from Latin libīdō, “lust, desire,” and first used a lot in psychology. It has nothing to do with liberty or with library, even though it starts the same way.

It它 was borrowed from Latin libīdō是從拉丁文libīdō借來的, “lust, desire,”意思是「慾望、渴望」, and first used a lot in psychology最早大量用在心理學裡. It它 has nothing to do with liberty or with library跟liberty自由或library圖書館都沒有關係, even though it starts the same way雖然開頭拼法看起來一樣.
