Language Geeks!!!

I need a question answered..... Is there a specific term for a phase such as "leap of faith", "pushing the limit" or "end of the rope"....

I am trying to explain to PJ that these are phrases that don't just have a literal meaning and I am only able to descibe them as a figure of speech and that seems a little weak. Help me out??

N was kind enough to join me for a walk in the woods today to hunt fungi... I have only started to ID these ones but I wanted to show off my photos. crossposted to mycology
