[Avodah] The term 'erusin'

[Micha Berger]

But WRT eruv or challah, there is no problem of "yatza shemah ba'ir
'mequdeshes', mequdeshes" (Gittin 88b). This was mentioned in the
Nitei Gavriel, as quoted by RYG at the top of the discussion.

One would have to prove that lashon benei adam is the criterion here,
so that the current usage of "eirusin" doesn't create a qol of being
"mequdeshes". I think you can, but it does make the case far less
trivial than simply wanting to resist language drift.

Tir'u baTov!
-Micha
