You almost only see it in print, in names and addresses, where space is tight: “the American Heart Assn.” People do not say “assn” out loud; they still say “association.” Though actually, English is messy with these shortcuts — Assoc. is another written short form of the same word, and Ass. can mean assistant, which is a different thing, so read the full name if you can.

You你 almost only see it in print幾乎只會在印刷品上看到這個縮寫，in names and addresses在名稱和地址裡，where space is tight因為那些地方空間有限："the American Heart Assn."像「the American Heart Assn.」。People人們 do not say "assn" out loud不會把 "assn" 唸出來；they他們 still say "association."還是會說「association」。Though actually不過事實上，English英文 is messy with these shortcuts這類縮寫用得有點亂——Assoc. Assoc. is another written short form of the same word是同一個字的另一種書面縮寫，and而 Ass. Ass. can mean assistant可以指 assistant（助理），which這 is a different thing是完全不同的東西，so所以 read the full name if you can可以的話最好看完整的名稱。
