It is a plain, everyday adjective, not fancy and not unkind. Before a noun, careful English likes the hyphen: a medium-sized car. After the verb you can say “the car is medium-sized,” or often just “medium.” Medium by itself already does a lot of this work (“a medium coffee”), so medium-sized is the form you reach for when you want to be extra clear that you mean size.

It它(這個字) is a plain, everyday adjective是一個平實、日常的形容詞, not fancy and not unkind不花俏，也不帶貶意。Before a noun放在名詞前面時, careful English講究一點的英文 likes the hyphen喜歡加連字號: a medium-sized cara medium-sized car。After the verb在動詞後面, you can say你可以說 "the car is medium-sized,"「the car is medium-sized」, or often just "medium."或者常常就直接說「medium」。MediumMedium by itself單獨一個字 already does a lot of this work就已經能表達很多這個意思 ("a medium coffee")（「a medium coffee」）, so medium-sized所以medium-sized is the form you reach for就是你要用的形式 when you want to be extra clear that you mean size當你想特別講清楚你指的是大小的時候。
