Most Dutch plurals add -en, and a smaller group adds -s - typically words ending in an unstressed -el, -em, -en, -er or a vowel. Spelling shifts to keep the vowel sound: maan becomes manen, but man becomes mannen.
Examples
- Ik heb twee broers en drie zussen.
- I have two brothers and three sisters.
- De hotels zijn vol.
- The hotels are full.
- Twee koffie, alstublieft.
- Two coffees, please.
The mistake to avoid
Doubling the consonant keeps a short vowel short - man to mannen, not "manen", which means moons.
Where this fits in
Numbers, days, time, Dutch A1: Count, talk about days and months, give the time, and handle numbers in real situations.
