Huszon

Huszon is a Hungarian numeral prefix used to form the numbers 21 through 29. It derives from húsz, meaning twenty, and appears in compound numbers before the unit digits. The prefix is used to create a single, commonly spoken form for the 20s range.

In standard spelling, the 20s numbers are formed by combining huszon with the corresponding unit:

- 21: huszonegy

- 22: huszonkettő

- 23: huszonhárom

- 24: huszonnégy (alternative spellings such as huszonnégy may appear in some varieties)

- 25: huszonöt

- 26: huszonhat

- 27: huszonhét

- 28: huszonnyolc

- 29: huszonkilenc

Huszon is not used for numbers outside the 20s; for example, 30 is harminc, 31 is harmincegy, and so on. The form huszon is therefore a specific morphophonemic solution in Hungarian for the 21–29 range, functioning as a fused variant of húsz plus the following digit. The usage is prevalent in everyday speech and most formal writing that numbers in the 20s range.
