Is ELU tag guidance required to "accord" with tag guidance at Linguistics.SE? I ask because a recent update-change I made to the tag guidance for etymology was rolled back by a moderator, with the comment "Make sure the usage-guidance excerpt accords with the one used on Linguistics.SE".
My effort was intended to update existing tag guidance to conform with actual use of the tag on ELU. I changed the guidance to the 'loose definition' of etymology offered by Gerald Cohen in the preface to Etymology and Linguistic Principles:
The search for the origin of linguistic features: words, idioms, morphological elements, writing systems.
The tag guidance was (before I changed it)
Etymology is the history of the origin of words and phrases.
My change seemed to cover the range of legitimate uses of the etymology tag here at ELU, and especially included "idioms, morphological elements, writing systems", that is, linguistic features of English that are left out of the current guidance, which is
the study of the history of words, their origins, and how their forms and meanings have changed over time.
In my ignorance, I (1) didn't know our tag guidance had to "accord" with the guidance at Linguistics, (2) don't see how the change I made doesn't "accord" with and even improve on the Linguistics tag guidance, and especially (3) think questions focused on "history" are more appropriate at History.SE.
