How is everyone doing?
I got a question on idioms: What is allowed and what's not?
In my understanding,
so far are allowed:
1) idioms (break the ice)
2) historical phrases (after us the deluge)
3) proverbs (better late than never)
4) phrasal verbs (go for)
1) one word entries
2) entries based on figurative meanings of the words
3) slang (knowledge-box for head)
Please correct me if I'm wrong,
