This is a link to an extensive glossary LGPTQIA terms, created at UCLA.
As the introduction to this glaossary, explains,
"A note about these definitions: Each of these definitions has been carefully researched
and closely analyzed from theoretical and practical perspectives for cultural sensitivity,
common usage, and general appropriateness. We have done our best to represent the
most popular uses of the terms listed; however there may be some variation in
definitions depending on location. Please note that each person who uses any or all of
these terms does so in a unique way (especially terms that are used in the context of an
identity label). If you do not understand the context in which a person is using one of
these terms, it is always appropriate to ask. This is especially recommended when
using terms that we have noted that can have a derogatory connotation"
