"She hears birds."
Translation:Ze hoort vogels.
I had to go and read about it, since it's still tricky for me ;)
With most nouns, you add -en to make the plural form.
Now, to know whether to add -s or -en, there are some guidelines (7).
√ nouns ending in a single open/long vowel (a, i, o, u, y)
√ names of letters and acronyms.
√ doffe e (an e that sounds as a schwa, the e in de). ziekte > ziektes (Careful! Some take -en to form the plural: kapelle>kapellen)
√ some nouns ending in double e (thee>thees -careful! Because zee>zeeën)
√ nouns ending in an unstressed vowel combination (mainly, -ie)
√ unstressed endings: -el, -em, -el, -erd, -aar, -aard, -um (this one, coming from Latin, can change into -a, as in museum>musea)
√ stressed endings -eur and -foon
√ person's titles or professions that end in -oor and -ier
√ loan words that form their plural with an -s in their original language.

Ok so it's clear it's not the plural now, but what does Vogelen actually mean? O_o
