How common are the "phile" words?

[alpacinou]

I've found a list of words which suggest a person loves a particular thing:



How common are they?

For example, if I love stars and I say I'm an astrophile, would I be understood?

 

[5jj]

Probably not.

 

[Amigos4]

I would understand what you were saying! Astrophile

 

[jutfrank]

You would be understood by some proportion of the population, yes. I wouldn't like to say what size.

The suffix -phile, generally speaking, is widely understood.

 

[Rover_KE]

... as is its close antonym — -phobe.
