Okay, I merged them, and changed the tag wiki (feel free to edit this to something better):
For questions about measure words and classifiers (量词), e.g., 个, 双, 张
I'm confident that few people (if anyone) will object to me merging these tags. I feel it's clear from the examples that they're used interchangeably. However, I don't know for sure whether to call it classifiers or measure-word.
For now, I'll choose measure-word because:
- I feel beginners are often taught that 个 etc. is a measure word, so they're not going to think to use classifiers, however...
- I spoke with Tang Ho about this, and (assuming I've understood things correctly) some people are instead taught that 一个 is a measure word in which 个 is the classifier (this may even be the linguistically "correct" terminology). Nevertheless, the people who understand this distinction can probably understand using measure-word as an approximation for classifiers for the purposes of tagging.
Basically, it's my best guess at the time of writing. If the community thinks classifiers is better, it's easy to rename (but please create a meta post).
