You’ve probably heard the noun harrastus before, right? It means ‘hobby’. But what about the verb harrastaa? It’s a verb to which there’s no clear equivalent in English. You could say it means something like “to have as a hobby” or “to do as a hobby”. I’ve written down some examples on how to use the verb.
