For something I'm writing I'd really like to uses the term northern hemispherean to describe someone who lives north of the equator. It just sounds cool. Not surprisingly, spell check flagged hemisperean. There … did it again.

I know it's not in accepted use (I searched for it). My question is on the suffix, since I don't want to "violate" some general rule I'm not aware of. I used "ean" simply because "hemisphere" ends with an "e." Then I got started thinking maybe "ian" might be better.

Any insights or input welcome. Thanks.

Thanks for the input. I also thought of "European," and a few other adjectives where the root ended with an "e," and that pattern was what influenced my choice of the "ean" suffix.

Yeah, I see that typo now. I had told spell check to ignore hemispherean when I was composing the original article, but not to add it (just yet). Now I'm wondering if the spell check in this forum is the same spell check that runs locally through MS Office, or if it's a separate system in this forum. Never really understood how that works. Spell check flagged it again in this response.

My article doesn't go online till tomorrow. I'll post a link then for those interested. But unless someone else weighs in with a strong argument for using the "ian" suffix, I'm gonna go with "ean."
