Learn Dutch: Het station is best toegankelijk voor iedereen. - The station is quite accessible for everyone.

In Dutch, best is indeed the superlative of goed (good). However, when placed right before an adjective like toegankelijk, it acts as an adverb of degree. In this context, it means 'quite', 'fairly', or 'pretty'. It usually adds a positive or pleasantly surprised tone, much like saying 'pretty accessible' in English.

Could I use nogal or vrij instead of best in this sentence?

Yes, but it changes the tone slightly. Best usually sounds positive or encouraging. Vrij is a bit more neutral, simply stating it is 'fairly accessible'. Nogal also means 'quite' but can sometimes carry a slightly negative or heavier undertone, which wouldn't make as much sense when talking about a station being happily accessible to everyone.

How is the word toegankelijk formed and pronounced?

It is built from the noun toegang (access or entrance) and the common suffix -lijk, which turns words into adjectives (similar to '-able' in English). Remember that the -lijk suffix is always pronounced as 'luk', so the word sounds like 'too-gang-kuh-luk'.

Why does voor iedereen come at the end of the sentence?
