nyolcvanöt

Nyolcvanöt is the Hungarian cardinal number for the value 85. It is written as nyolcvanöt and pronounced with the final ö sound in öt. The number is formed by combining nyolcvan, meaning eighty, with öt, meaning five, reflecting the common Hungarian pattern of composing tens and units.

In mathematical terms, nyolcvanöt is an odd composite number, equal to 5 × 17. Its decimal representation is 85; in other numeral systems it appears as LXXXV in Roman numerals, 1010101 in binary, and 0x55 in hexadecimal. The name itself illustrates how Hungarian builds numbers from a tens stem plus a unit.

Grammatically, nyolcvanöt can be used as a cardinal numeral in ordinary counting, ages, measurements, and similar contexts. The ordinal form is nyolcvanötödik, used to denote the 85th position in a sequence (for example, the 85th day, the 85th edition). When referring to years in a full form, Hungarian typically expresses the year with all digits, as in ezerkilencszáznyolcvanöt for 1985, rather than using nyolcvanöt alone.
