I can say a number up to a thousand and understand it by ear, say how old I am, and ask someone's age.
Ik ben vierendertig: numbers up to a thousand
Ik ben vierendertig: numbers up to a thousand
Why: to say your age, a house number, a number above twenty.
The tens are in the table. Three change the stem: dertig, veertig, tachtig. Don't mix them up by ear: dertien — 13, dertig — 30; zeventien — 17, zeventig — 70.
A compound number is written as one word, and the ones come first, joined by en: “one and twenty” — eenentwintig, “four and thirty” — vierendertig. If three vowels meet at the join, the e gets a trema: tweeëntwintig, drieëndertig. You don't have to type the trema: the answer still counts.
Hundreds and thousands take no een: honderd, tweehonderd, duizend; 105 — honderdvijf, 250 — tweehonderdvijftig.
Age is said with zijn: Ik ben vierendertig. Hoe oud ben je? You can add jaar; after a number it doesn't change: vijf jaar.
Common mistakes:
• ×twintigeen, ×een en twintig → eenentwintig;
• ×Mij is 34 → Ik ben 34; ×Ik heb 34 jaar → Ik ben 34 jaar.
Tens, a hundred, and a thousand
Three tens change the stem: dertig, veertig, tachtig.
| Number | Word |
|---|---|
| 20 | twintig |
| 30 | dertig |
| 40 | veertig |
| 50 | vijftig |
| 60 | zestig |
| 70 | zeventig |
| 80 | tachtig |
| 90 | negentig |
| 100 | honderd |
| 1000 | duizend |
Compound numbers: the ones come first
One word, with en between the parts. After twee and drie, the join takes a trema.
| Number | Word | How it's built |
|---|---|---|
| 21 | eenentwintig | 1 + en + 20 |
| 22 | tweeëntwintig | 2 + en + 20, trema |
| 23 | drieëntwintig | 3 + en + 20, trema |
| 34 | vierendertig | 4 + en + 30 |
| 105 | honderdvijf | 100 + 5, no en |
| 250 | tweehonderdvijftig | 2 × 100 + 50, no en |
| 1990 | negentienhonderdnegentig | 19 × 100 + 90: years are said in hundreds (recognition only) |
