This module generates content for several etymology templates. They include:

{{etyl}}

Also, the following specialized borrowing templates (not including {{bor}}/{{borrowed}} itself):

Miscellaneous etymology templates that take a single term parameter:

{{abbrev}}
{{back-formation}}
{{clipping}}
{{ellipsis}}
{{initialism}}
{{rebracketing}}
{{reduplication}}
{{spoonerism}}
...

Miscellaneous etymology templates that take no term parameter:

{{onomatopoeic}}
{{uncertain}}
{{unknown}}
...

Some templates that used to be here but have now been moved to submodules:

Module:etymology/templates/cognate: {{cognate}}, {{noncognate}}
Module:etymology/templates/derived: {{derived}}
Module:etymology/templates/inherited: {{inherited}}
Module:etymology/templates/borrowed: {{borrowed}}
Module:etymology/templates/doublet: {{doublet}}
Module:etymology/templates/descendant: {{descendant}}, {{descendants tree}}
