Questions & Answers about Musimy się pozbyć problemu.
Musimy means we must / we have to. Its base form is musieć (to have to / must).
This is the 1st person plural form, so:
- muszę = I must
- musisz = you must
- musi = he/she/it must
- musimy = we must
- musicie = you all must
- muszą = they must
So Musimy... starts the sentence with We have to...
Się is part of the verb phrase pozbyć się, which means to get rid of.
You should learn pozbyć się as a single unit, not as pozbyć plus a separately meaningful się in this sentence. Many Polish verbs are used with się, and often English speakers just need to memorize them that way.
So:
- pozbyć się = to get rid of
- musimy się pozbyć = we have to get rid of
Even though się often suggests a reflexive idea, here the whole expression simply means get rid of, not literally rid ourselves in a word-for-word way.
