How 2421 is built in Italian
Place-value sum: 2000 + 421 = 2421.
- 2 × 1000 = 2000 → duemila.
- thousands (2): 2 uses the basic form due.
- 421 → quattrocentoventuno.
- final group (421): 4 × 100 gives quattrocento. Join quattro to cento.
- Then attach the remainder 21 (ventuno) to obtain quattrocentoventuno.
- Inside final group (421), 21 = 20 + 1: venti + uno becomes ventuno.
The number is written as one lowercase word, with no spaces or hyphens.
