Idiom:  On thin ice (meaning)

Look at the picture and try to guess the meaning of the idiom 'on thin ice.'   

(skating / treading / walking) on thin ice:   1. in a dangerous position where you could fall or have an unfavorable result; 2) in a risky or uncertain situation.


If you walk, tread or skate on thin ice there is a good chance that you might fall through the ice and into the freezing cold water. It's a dangerous and risky position to be in and it is uncertain exactly when you might fall and what the result might be.

So literally, on thin ice means you are standing on ice that is too thin to support your weight (and you're most likely to fall through the ice).

Idioms use figurative meanings of course—so on thin ice means being in a risky, dangerous or uncertain situation.
