|Notes:||A New Year stem.
This is a rather simple one, it was not subject to mutations and alterations through the history, so has been preserved in various Indo-European groups. The semantic closeness of the meaning "new" to "fresh" and "early" can be proved by substitutes of this very stem by stems with meanings "young" (Latvian jauns) or "fresh" (Scottish Gaelic ur).
Nevertheless, the second consonant of the stem -w- disappeared in several modern and even ancient tongues, which is natural according to their phonetic systems (e.g. Greek, where Indo-European w steadily disappears or turns into aspiration).
