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.
live high on the hog: have the best of everything
Example:
After barely getting by for years, Steve won the lottery and has been living high on the hog ever since.
lock the barn door after the horse has been stolen: be careful or try to make something certain after it is too late
Example:
After the scandal broke, the politician tried to minimize damage to his reputation by promising to make all his campaign finances public. That’s like locking the barn door after the horse has been stolen, as far as I’m concerned.
