Idioms are fixed expressions whose meaning is not fully predictable from the individual words. They often sound “literal” but actually communicate a figurative idea, feeling, or social signal. Because idioms are conventional, you learn them as whole phrases and choose them based on situation and tone.

Many common idioms function as quick reactions in conversation, showing agreement, surprise, doubt, or resignation. The key is matching the idiom to your attitude: some sound calm and practical, others sound dramatic or humorous. Use these when you want to respond naturally without a long explanation.

No way	Strong surprise or disbelief	No way, you met her in person?
You bet	Confident yes	Are you coming tomorrow? You bet.
It depends	Not a yes or no	Can you finish today? It depends.
Fair enough	Accepting a point or decision	I need more time. Fair enough.

These idioms help you describe beginnings, delays, and endings in a natural, conversational way. They are especially common in work and daily planning. Use them to talk about timing without sounding overly formal.

Money idioms often compare cost to worth, or describe saving and spending habits. Many are casual and common in daily conversation. Use them to express value judgments without giving exact numbers.

Use idioms when they fit the situation, the relationship, and the level of formality. Many idioms sound natural in friendly conversation but can feel too casual in formal writing. Prefer idioms you understand clearly, and avoid mixing two different idioms into one expression.

Rule	Example
Match formality to context	Casual: Let’s call it a day. Formal: Let’s stop for now.
Use an idiom only if you know the meaning and tone	He gave me the cold shoulder means he ignored me.
Treat common idioms as fixed phrases	Correct: cost an arm and a leg. Not: cost an arm and a foot.
Do not combine different idioms	Correct: bite the bullet or rip off the bandage, not a mix.
Pay attention to who uses it and when	In a meeting: We’re on the same page. With friends: No way.
