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

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

Miscellaneous etymology templates that take a single term parameter:

Miscellaneous etymology templates that take no term parameter:

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