However, "leir" is not a common word in the English language. It is an archaic word meaning "a kind of coarse cloth" or "a kind of wild pear."
It's much more likely that you are thinking of a different word that sounds like "leer" but has a different meaning, such as:
* leer: to look at someone with a lascivious or sly expression.
* lier: a person who tells lies.
* year: a period of 365 or 366 days.
If you can provide more context, I might be able to help you figure out which word you're looking for.
