-isto

From Latin -ista.

• IPA^(key): [ˈisto]
• Rhymes: -isto
• Hyphenation: is‧to

-isto

1. a person who belongs to a profession occupied with

   ‎maro (“sea”) + ‎-isto → ‎maristo (“sailor”).

-isto is not as broad as English -ist.

It is important to distinguish between an -anto, someone who is doing something, and an -isto, someone whose job it is to do something. For example, if you are cooking dinner, you are a kuiranto (“cook (someone who is cooking)”). If you are employed as a chef, you are a kuiristo (“cook (by profession)”).

Also note that in Esperanto, membership is denoted by -ano. For example, a colonist is a koloniano, not a *koloniisto.
