tugur

Icelandic

tugur m (genitive singular tugar or (sometimes proscribed) tugs, nominative plural tugir)

Compound adjectives referring to someone's age or by some unit (of measurement) are composed of either -tugur (20-70s, 90s archaic/obsolete) or -ræður (80s-100s, 70s archaic/obsolete). The adjective tólfræður is only used to refer to something by a unit, not a person by age.
