Talking about home-made food
Is this phrase called compound adjective?
If so, Do we always have to put a hyphen between the words which are considered an adjective, because i've noticed that sometimes you put a hyphen but other times you don't.
I hope that you give us a lesson about compound adjectives

We can also "BLOW" or "TAKE" the LID OFF something, Or "LIFT the Lid ON something" which means "to cause something bad that was previously kept secret to be known by the public".

Can you please suggest me the way I can score band 9 in IELTS. Please share the tips if you have. Is it necessary to take british council classes for IELTS or watching BBC will do the job?

I couldn't keep a lid on my feelings about her so I keep texting her all day long.

I heard that he would get the promotion from the boss. But keep a lid on it until there is an official announcement.
