Learn Danish: Optikeren laver nok en synsprøve i dag. - The optician will probably do an eye test today.

Danish frequently uses the present tense to talk about the future. When combined with an adverb of probability like nok and a time phrase like i dag, it naturally implies a future expectation, so 'will do' or 'is probably going to do' is the best English equivalent.

Doesn't the word nok mean 'enough'? Why does it mean 'probably' in this sentence?

You are right that nok means 'enough' in phrases like det er nok (that is enough). However, in Danish it is also used extensively as a modal particle to soften a statement, expressing expectation, probability, or reassurance. In this context, it translates to 'probably' or 'most likely'.

Could I use gør instead of laver to say the optician 'does' a test?

No, laver is the correct verb here. While both words mean 'do' or 'make', laver is used when producing, preparing, or conducting something specific, like an eye test (en synsprøve). Gør is used more for abstract actions, states of being, or set phrases like at gøre rent (to clean).

What are the parts that make up the word synsprøve?

It is a compound noun formed from syn (sight or vision) and prøve (test or trial). They are joined by a linking -s-, which is a very common way to glue nouns together in Danish to make pronunciation flow better.
