Words that have the same sound but different meanings

In linguistics, a homonym is words that share the same pronunciations but have different meanings, whether spelled the same or not.  Homographs are words that share the same spelling, regardless of their pronunciation. Homphones are words that share the same pronunciation, regardless of their spelling.
The relationship between a set of homonyms is called homonymy. eg. stalk (part of a plant) and stalk (follow/harass a person) and the pair left (past tense of leave) and left I (opposited of right). Some time the distinction between "true" homonyms are unrelated in orgin, such as skate (glide on ice) and skate (the fish)
Poysenmous homonyms or plysemes which have a shared origin, such as mouth (of a river) and mouth (of an animal).

In non-technical contexts, the term "homonym" may be used (somewhat confusingly) to refer to words that are either homographs or homophones. The words row (propel with oars) and row (argument) and row (a linear arrangement of seating) are considered homographs, while the words read (peruse) and reed (waterside plant) would be considered homophones; under this looser definition, both groups of words represent groups of homonyms.

The adjective homonymous can additionally be used wherever two items share the same name,independent of how close they are or aren't related in terms of their meaning or etymology.
