their derivatives in -tōrius). Some scholars have noted that the legendary King Arthur's name only appears as Arthur, Arthurus, or Arturus in early Latin Arthurian texts, never as Artōrius (although the Classical Latin Artōrius became Arturius in some Vulgar Latin dialects). However, this may not say anything about the origin of the name Arthur, as Artōrius would regularly become Art(h)ur when borrowed into Welsh. The commonly proposed derivation from Welsh arth "bear" + (g)wr "man" (earlier *Arto-uiros in Brittonic) is not possible for phonological and orthographic reasons; notably that a Brittonic compound name *Arto-uiros should produce Old Welsh *Artgur (where -u- represents the short vowel /u/) and Middle/Modern Welsh *Arthwr and not Arthur (where -u- is a long vowel /ʉː/) In Welsh poetry the name is always spelled Arthur and is exclusively rhymed with words ending in -ur—never words ending in -wr—which confirms that the second element cannot be [g]wr "man"). An alternative theory, which has only gained limited acceptance among scholars, derives the name Arthur from the Latin Arcturus (the brightest star in the constellation Boötes, near Ursa Major or the Great Bear), which is the latinisation of the Greek Ἀρκτοῦρος (Arktouros) and means Bear Guardian from ἄρκτος (arktos "bear") and οὖρος (ouros "watcher/guardian"). This form, Arcturus would have become Art(h)ur when borrowed into Welsh, and its brightness and position in the sky led people to regard it as the "guardian of the bear" and the "leader" of the other stars in Boötes. Avestan /arta and its Vedic equivalent both derive from Proto-Indo-Iranian *ṛtá- "truth", which in turn continues Proto-Indo-European * "properly joined, right, true", from the root *.
