Pier and peer are homophones, meaning they sound alike but are spelled differently, and mean different things. They are also easily confused words. The spell-check application in word-processing software doesn’t catch words that are spelled correctly even if another word should have been used in that context.
Pier is a noun meaning referring to an elevated structure built out over the ocean. It’s used as a lookout point for people on a shoreline; it also refers to the supporting pillars of such a structure.

Peer is a noun meaning another person of your age group, school group, or fellow employee. It’s plural, peers, means many of the people in these groupings.
Peer can also be a verb, meaning to look, usually in a intrusive manner.
The following sentences use these words correctly:
