Learn Swedish: Gemenskapen är stark när vi förlåter varandra. - The community is strong when we forgive each other.

Varandra means "each other" and it is a fixed word. Unlike reflexive pronouns (like mig, dig, sig) that change depending on who is doing the action, varandra always stays exactly the same whether the subject is "we", "you" (plural), or "they".

Is gemenskapen related to other words? It looks like a compound word.

Yes! It comes from the adjective gemensam, meaning "common" or "mutual". The suffix -skap works just like "-ship" in English (like in "friendship"). So en gemenskap is a community or fellowship, and the -en on the end makes it "the" community.

Why is the word order normal in the second half of the sentence (när vi förlåter)? Doesn't när change the word order?

The word när (when) starts a subordinate clause. In a Swedish subordinate clause, the subject (vi) still comes right before the verb (förlåter). The word order only gets tricky here if you add a word like inte (not), which would squeeze in between the subject and the verb: när vi inte förlåter varandra.

Why is the adjective stark instead of starkt?
