"Hij gebruikt ze graag."
Translation:He likes to use them.
Out of curiosity, would this be 'them' people or 'them' things? Or both depending on context?
Is there a way to tell if "ze" is singular or plural in this sentence? Normally I'd check the verb conjugation but that won't work in this situation.
'Ze' is the unmarked version of 'hen', meaning 'them'. The unmarked version of 'her' is the same as the marked pronoun: 'haar'. That is, in Dutch spoken in the Netherlands. In Flanders, the Dutch speaking region of the Netherlands, 'ze' can also mean 'her'. Since this course is teaching us the standard language, I assume that we can only translate 'ze' as 'they'.
"Graag" is sometimes translated as "gladly" or "with pleasure." From its use, however, I gather that those don't really fit in well when translating the word into English. It's sort of "He uses them with pleasure," but more like "He gets enjoyment from using them," and really just translates best as "He likes using them."
