If 'enige' and 'paar' both mean 'few/a few' then how are they used in different contexts? Or can they be used interchangeably?
In this case, they can be used interchangeable: either "een paar" or "enige" is corrected in front of "meisjes".
Yes, it can mean both the strict a pair of… or the loose a few. But the strict meaning of een paar is more common with things that typically come in pairs, like: een paar schoenen (a pair of shoes), een paar oorbellen (a pair of earrings), een paar handschoenen (a pair of gloves).
I just have been thinking the same, but before I haven't seen anyone saying that you just have explained here, I have been having a doubt in my head. Thank you :)
