I would be surprised if this didn't come up when discussing the different connotations the words might have to English speakers.

Chances are, if you live in an English-speaking culture, if you hear astrologian, you think "Theologian of the stars! How exciting!" but if you hear astrologer or astrologist, you think, "Like, the person who looks at my sign and says, 'you don't like being contradicted' and 'you prefer spending time with close friends?'"
