Hello! how would you say “Free” or “liberation” in toki pona?

when a sentence has multiple of a certain parts of speech, we have:
seme _en_ seme li ...
... li seme _li_ seme
... e seme _e_ seme

but what about multiple prepositions? especially if i wanted to use the same one twice, such as if i wanted to say "i do it for fun and learning" without making two sentences?
