Questions & Answers about Ponieważ komisja ma nowy plan, wszyscy członkowie muszą przyjść na spotkanie.
Why does the plural of członek (member) end in -owie?
Because it refers to a group of people by their role or title! Masculine personal nouns for titles, professions, and family members often take the -owie suffix in the nominative plural (just like profesorowie or ojcowie). Notice also that the e in członek disappears when adding the ending, making the stem członk-.
Why is the word for 'all' wszyscy instead of wszystkie in this sentence?
Because członkowie is a masculine personal (virile) plural noun, so any adjectives or pronouns describing it must also take the virile form. Wszyscy is the virile form, used for groups with at least one male. Wszystkie is the non-virile form used for women, animals, or objects.
Why use ponieważ here instead of the simpler word bo (because)?
In Polish, you should generally avoid starting a sentence with bo. When the 'because' or 'since' clause comes at the very beginning of the sentence, as it does here, you should use ponieważ instead.
Could I say pójść instead of przyjść for 'to come'?
