@georgia Not necceseraly, depends on the definition.

Also as for no body wanting that, I would certainly be ok with that and it makes way more sense to me.

Language is decided by historical usage, it isnt something we get to "decide" for words that already exist (only new ones we make).

As such we already had a definition for the word that included pluto. If they felt the word wasnt useful technically instead of destroying the old word and redefining it what they should have done is came up with a new word they could have assigned any technical definition they wanted to it. Thats how it is done in almost every other discipline of science.
