Actually I look for some English idioms, or as we say "proverbs" or "popular expressions". But I wonder if we use a lot of these expressions during a casual conversation that we could have with a new person we met in the street or somewhere else.
Some of them look very old school and it may be weird for me (I'm young) to use them with a group of young people.
Also, I would like to know if people use idioms in formal conversation or in academics test as TOEFL or TOEIC.
Some concerned idioms : -fish out of water -in the nick of time/ Instead of "We are almost late" -Draw lines/ Instead of "set some limits" -Cut corners -Play it by the ear/ Instead of improvise -Between a rock and a hard place -Bite a bullet Etc...
I won't list all of them here but you can get the gist.
