Set phrases are commonly used expressions that are often difficult to translate word for word. They are an essential part of any language as they allow people to express themselves in a succinct and efficient manner. Synonyms for set phrases include idioms, sayings, proverbs, cliches, and expressions. Idioms are phrases that have a figurative meaning that differs from their literal meaning, such as "it's raining cats and dogs." Sayings are short expressions that convey a message or wisdom, such as "actions speak louder than words." Proverbs are simple and timeless sayings that offer guidance or advice, such as "slow and steady wins the race." Cliches are overused phrases that have lost their original meaning, such as "think outside the box." Expressions are phrases that convey a specific idea or sentiment, such as "thanks a million."".
