Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words.
smell a rat: be suspicious, feel that something is wrong
Example:
The accountant knew he smelled a rat when he examined the books and found some money was missing from the bank account.
straight from the horse’s mouth: directly from the person or place where something began
Example:
Did you know that Jack and Mary are moving to Georgia next month? I heard it straight from the horse’s mouth.
