Questions & Answers about Vi har bara målat själva räcket i skateparken.
How does själva work in this sentence, and why does räcket have a definite ending?
själva is an emphatic determiner meaning 'the actual' or 'the [noun] itself.' When placed before a noun to emphasize it like this, it always requires the noun to be in its definite form. That is why we use the definite räcket instead of the indefinite ett räcke.
Since ett räcke is an 'ett-word', why don't we use självt?
When used before a noun to mean 'the actual [noun],' the word freezes into the form själva. It does not change to match the noun's gender or number. You only use själv or självt when it acts as an adjective meaning 'by oneself' placed after the noun or pronoun.
Why is the adverb bara placed between the two verbs?
This is the standard word order for main clauses in Swedish. Sentence adverbs like bara go directly after the first, conjugated verb (har) and before the second verb (målat).
