I have this in a sentence:

It seems the most base opinion...

as in it seems the most basic/fundamental opinion...

google docs tells me its wrong but when I try to google it just tells me about the slang word based or, if I clarify base more, about the base of mountains and such. Basically I just think it sounds like a fun and concise way to get the point across in my essay but obviously don't want to use something I don't understand.

Is that phrasing correct? or should I change it
