What is the meaning of this idiom and how would we use this idiom in a sentence,
whts the correct way of using it?
I have heard that idiom used in a sarcastic manner. For example, if a woman goes into a dusty small town police station dressed in furs and jewels, the sheriff might say, "I'm going to go out on a limb and say you're not from around here."
GO OUT ON A LIMB
It means to put oneself in an isolated or disadvantaged position in one's support of someone or something. Like if you go out on a limb, you state an opinion which is very different to most other people.
