The word tag is meaningless and subject to abuse. Its tag wiki is not helpful either:
The tag is for the question of any kind but related to a 'word' in general.
English.SE has no questions tagged [word]. Instead, there are more specific tags such as [word-choice], [word-usage], and [meaning].
There are currently 64 questions tagged with word. Most of them appear to be questions about either [word-choice] or [meaning]. It's not too late to retag these questions before the situation gets out of hand. I think it's worth harmonizing the tags with English.SE to facilitate migration of questions between sites.
