First, i want to thank ESL Forum for creating a good website for people all over the world who need improve their English skill.
Now, i have a BIG problem. There are many words or phrases which are in the same meaning in English.
Example1 : To see eye to eye = To agree
Example2 : To take it easy = To relax
Teachers, can you list some phares which are usually used? Thx you very much. I'm grateful for your help !
PS: Sorry for my bad English. My mother touge is Vietnamese.
