Pair, pare and pear are homophones. I sometimes see pair used when pare or pear would be appropriate. It depends on the context, but it can be very confusing when these words are used incorrectly.
Pair
- a set of two
- a thing with two joined parts (e.g. a pair of shorts)
- to put together to form a pair
Pare
- to trim by cutting away the outer edge or layer
- to reduce something
Pear
- the edible fruit and its tree
