Puritanism這個字, in the sense you need here在你這裡需要的意思上, means指的是 strict religious and moral attitudes嚴格的宗教與道德態度 — especially尤其是 a tight, unfriendly view of pleasure and sex對享樂和性很嚴苛、不友善的看法 — and the word is used to show disapproval而且用這個字通常帶著不認同的意味。

With a capital P, Puritanism also names the real historical movement of the Puritans in England and America in the 1500s and 1600s. Newspapers often blur the two: they say puritanism when they mean a modern killjoy mood, not a church.

With a capital P字首大寫的時候, Puritanism這個字 also names也指 the real historical movement真正的歷史運動 of the Puritans in England and America也就是16、17世紀英格蘭和美國清教徒的運動 in the 1500s and 1600s（16、17世紀）。Newspapers報紙 often blur the two常常把兩者混在一起: they say puritanism他們講puritanism, when they mean其實指的是 a modern killjoy mood一種現代掃興的氛圍, not a church而不是指教會。

The disapproving everyday use is the one to learn first; the history is the background, not a different spelling. It is heavier than “being a bit strict.” It suggests a whole moral climate that watches people, especially around the body.

The disapproving everyday use這種帶貶義的日常用法 is the one to learn first才是你要先學的, the history歷史那個意思 is the background只是背景知識, not a different spelling不是另一個拼法。It is它 heavier than "being a bit strict"比「有點嚴格」更重。It suggests它暗示的是 a whole moral climate整套盯著人看的道德氛圍 that watches people（盯著人看）, especially around the body尤其是在身體這件事上面。
