Questions & Answers about Skärmen är utbytbar, men inte batteriet.
How exactly is the word utbytbar built?
It uses the suffix -bar, which means "able to be" (like "-able" in English). The root comes from the phrasal verb byta ut (to replace or exchange). When turning a phrasal verb into an adjective, the particle (ut) moves to the front of the verb root (byt): ut + byt + bar.
Batteriet is an ett-word, so shouldn't the adjective be utbytbart?
The adjective utbytbar you see here is only agreeing with skärmen, which is an en-word. The second half of the sentence is shortened. If you wrote out the full thought, it would be: "...men batteriet är inte utbytbart." Since the adjective is dropped from the second half to avoid repetition, we only see the en-word form.
Why is the word order men inte batteriet instead of men batteriet inte?
When you shorten a contrasting clause like this by dropping the verb, the negation inte naturally sits before the contrasted noun. This matches the English structure "but not the battery." If you kept the verb, standard main clause word order would apply: ...men batteriet är inte [utbytbart].
Can utbytbar also be used to describe people, like a replaceable employee?
