Tax-Exempt Special Savings Account「免稅特別儲蓄帳戶」 TESSA stands for就是TESSA這個縮寫代表的全名. It was a kind of savings account in Britain這是英國的一種儲蓄帳戶, and it existed from 1991 to 1999存在於1991年到1999年之間

The deal was this: if you put money in a TESSA and left it there for five years, the government did not take tax on the interest the money earned. If you took the money out early, you lost that benefit. So it was a way for ordinary people to save a modest amount of money and keep all of it.

The deal was this規則是這樣: if you put money in a TESSA and left it there for five years如果你把錢存進TESSA，放滿五年, the government did not take tax on the interest the money earned政府就不會對這筆錢賺到的利息課稅. If you took the money out early如果提早把錢領出來, you lost that benefit就會失去這個好處. So it was a way for ordinary people to save a modest amount of money and keep all of it所以這是讓一般人存一筆不多的錢、又能全部留住的方法

In 1999 the government stopped opening new TESSAs and replaced them with ISAs (Individual Savings Accounts), which work in a similar way but with more freedom. So today the word is history.

You meet it when you read about British money in the 1990s, or when an older British person talks about how they saved back then. It is written in capital letters because each letter comes from a word, but people say it as a name, 'TESS-uh', not letter by letter. Note that Tessa is also a common woman's name in English (short for Teresa) — the account was probably named to sound friendly like that, and British newspapers at the time made jokes about it.

Note that Tessa is also a common woman's name in English (short for Teresa)另外，Tessa在英文裡也是常見的女生名字（Teresa的暱稱）, the account was probably named to sound friendly like that這個帳戶大概就是想借用這種親切的感覺來命名, and British newspapers at the time made jokes about it當時英國報紙還拿這件事開玩笑
