Usage notes

 * If combined with a number written with digits, a hyphen may be used in the compound word (e.g. 3jährig or 3-jährig); if combined with a word, no hyphen is used (e.g. dreijährig). However, the spelling reform rules of 1996 etc. proscribe spellings like 3jährig and prescribe spellings like 3-jährig and dreijährig.
