complement和compliment分別是什麼意思？
compliment vs. complement
Both words mean "complete"
發音一樣，這兩個詞的意思是“完整的”
compliment (v/n) - 稱讚
當動詞使用
例句：
If you want to be popular , always compliment people around you.
如果你想受歡迎，總是讚美你周圍的人。
當名詞使用
例句：
To give people a compliment can let you be more popular.
給別人一個讚美可以讓你更受歡迎。
complement (v/n) - 兩件事物搭配起來相當好

Complement VS compliment 雖然只差一個英文字母，但是這兩個詞的意思與用法差很多！而且這兩個詞都可以以動詞或名詞還使用，這就更讓人搞不清楚了～
Complement VS compliment
像中文一樣，英文也存在一些同音不同字，同字不同意的字詞。Complement和compliment就屬於同音不同字，它們的意思也是不一樣的。
Complement的中文是：補充、補助、補足、配襯。通常會使用於將某個原本沒有足夠數量，但是已經「補充」滿(足)了——的句子上。
Compliment的中文則是：讚美、稱讚、讚揚、恭維。通常是用來「稱讚」某些人、事、物的外觀、態度或事件。
範例
Complement: The dress you are wearing today complement your hair. （你今天穿的這件裙子跟你的頭髮很搭配。）
Complement: The file that I send to you today complements the document that I sent to you yesterday. （我今天傳給你的資料夾，是昨天那個的補充資料。）
Compliment: I take this as a compliment. （我將這句話當作是恭維。）
Compliment: When was the last time you complimented yourself?（你最後一次稱讚你自己是在什麼時候？）
結論
Complement和compliment雖然在發音上沒有什麼差別，但是意思上，這兩者差別非常大。一個代表「補足」，另一個則是「讚美」。
