Thinking the same thing :-? This sentence is little confusing at least. Wouldn't "fler or mera" (adjectives: more) be more clear to use in this example. I think that you can use fler as synonyme to flera, but as i said this seems little confusing.
Jag har fler/mera barn = I have more children
Jag har flera/många barn = I have several/many children
Or have i misunderstood something?
Thanks for the reply.
There was a little mix up with the answers :) I did this exercise with my tablet and it offered "I have more children" as answer to this exact sentence. It seems that at least here in the forum the answer is correct.
I think that JohnL. was talking about the same thing.
Mistakes happen :)
Regular ett nouns ending in a consonant behave like this:
ett barn 'a child'
barnet 'the child'
barnen 'the children'
And regular en nouns behave like this
en bil 'a car'
bilen 'the car'
bilarna 'the cars'
So yes, if you see a one syllable word after flera, you can tell that it is an ett noun.
If you just see the word barn out of context, you cannot tell. On the other hand, we normally don't use words in the singular without an article. So if you see a sentence like Barn äter you can tell that it means 'Children eat', because if it had been about something singular, we would have needed the article. Most possessive pronouns show whether it's plural or singular, but not all:
mitt/mina barn 'my child/my children' – you can tell the difference
hans barn 'his child' or 'his children' – the pronoun doesn't show the difference, so you can't tell.
