    Suffix - "ist" & "er"

    Hi, I'm studying how the suffix "ist" as in "psychiatrist" and the suffix "er" as in "phylospher" are used but when I see a profession that is new to me, such as "astonomy" how do I know whether to use "astonomist" or "astronomer"? Is there a rule?

    Thank You!

    Basically, you just have to look them up in a dictionary.

    ps. it's 'philosopher'.

    Re: Suffix - "ist" & "er"

    You also have the additional problem of -er/-or:

    farmer/farmor; acter,actor; adviser/advisor.

    Don't worry too much; native speakers sometimes have to use a dictionary.
