Why is it called a pet peeve if nothing to do with pets?

The term "pet peeve" does not literally refer to anything related to pets. It is a figurative expression used to describe something that causes annoyance or irritation, often a minor annoyance or a personal idiosyncrasy.

The origin of the term is not entirely clear, but it is believed to have originated in the United States in the early 20th century. One theory is that it may be a blend of the words "petty" and "peeve," with "petty" referring to something small or inconsequential and "peeve" referring to an annoyance or irritation.

Another theory suggests that the term may have been influenced by the expression "a pet aversion," which was used to describe something that a person strongly disliked or found disagreeable.

Over time, the term "pet peeve" became more widely used and took on a more general meaning, referring to any small or persistent annoyance or irritation.

Here are some examples of common pet peeves:

- People who don't use their turn signals when driving

- People who talk loudly in public places

- People who don't clean up after their pets

- People who are constantly late

- People who chew their fingernails
