for同from

請留意兩句雖然看似同樣意思"簡稱"，但寫法上
1. 是用動詞(被動式)is abbreviated (請查是否你串錯了t前面的a為s) xxx是由yyy被動動詞而成的結果
2. 是用名詞abbreviation而動詞是is作為確定的寫法xxx is yyy=xxx就是yyy

因此
1的前置詞是from(由)yyy而變成xxx
2的前置詞是for(代替)yyy的就是xxx

兩個for/from是因著句字的寫法意思和用那種句式而配合的，不能交換代用或轉換的，如要改寫全句的詞(動詞方式或用詞)都要改動：

另外除了abbreviation外同義的寫法常見的還有
WHO stands for World Health Organization.
Fridge is short for refrigerator.
HKSAR is the abbreviation of Hong Kong Special Adminstrative Region.
等等

兩個用法:

‘World Health Organization‘ is abbreviated to WHO.

WHO is the abbreviation for/of ‘World Health Organization’.

WHO stands for World Health Organisation.
Fridge comes from refrigerator.
