Ordinals and fractions

Ordinal numbers add -dik (with a linking vowel) to the cardinal number: három ('three') → harmadik ('third'), négy → negyedik. Only első ('first') and második ('second') are irregular, and worth learning as whole words.

Fractions reuse words you've already partly met: fél ('half'), a familiar face from telling time, plus harmad ('a third'), negyed ('a quarter' — also from telling time), usually combined with a number: kétharmad ('two-thirds'), háromnegyed ('three-quarters').
