An adjective suffix for “-full” mentioned in the Quendi and Eldar (Q&E) essay form 1959-60 (WJ/412 note #21) and appearing in words like alcarinqua “glorious” = “✱glory-full”. Tolkien indicated it had a variant -unqua where “forms using u were mainly applied to things heavy, clumsy, ugly or bad” (WJ/415 note #31).
Quenya
-inqua
glorious
-inqua
suffix. -ful, complete
-ima
suffix. -able, -ible, adjective suffix, apt to do
-ima adjectival suffix. Sometimes it is used to derive simple adjectives, like vanima "fair" or calima "bright"; it can also take on the meaning "-able" (PE17:68), as in mátima "edible" (mat- "eat"), nótima "countable" (not- "count") and (with a negative prefix) úquétima "unspeakable" (from quet- "speak"). Note that the stem-vowel is normally lengthened in the derivatives where -ima means "-able", though this fails to occur in cenima "visible" (q.v., but contrast hraicénima, q.v.) and also before a consonant cluster as in úfantima "not concealable" (PE17:176). "X-ima" may mean "apt to X" (when the ending is added to an intransitive verbal stem), as in Fírimar "mortals", literally "those apt to die" (WJ:387). The adj. úfantima "not concealable" (PE17:176) also appears as úfantuma (PE17:180), indicating the existence of a variant ending -uma (possibly used to derive adjectives with a "bad" meaning; compare the ending *-unqua next to -inqua, q.v.)
alcarin
glorious, brilliant
alcarin adj. "glorious, brilliant" (shorter form of alcarinqua, q.v.) (PE17:24), hence Alcarin masc. name (or title) "the Glorious", title taken by Atanatar II of Gondor, also name of one of the Kings of Númenor (Appendix A).
alcarin
proper name. Glorious
Tar-Alcarin was the 17th ruler of Númenor (LotR/1035, UT/222). His name is simply the shortened form of alcarin(qua) “glorious”. Alcarin “Glorious” was also a sobriquet for Atanatar II, the 16th king of Gondor (LotR/1038, 1045).
alcarinquë
proper name. Glorious
A star (S/45) or possibly the planet Jupiter (MR/435). Its name is simply the noun form of the adjective alcarin(qua) “glorious”, or possibly a feminine form as suggested by Vyacheslav Stepanov (many star names on MR/435 seem to be gendered).
-inqua adjectival ending, seen in alcarinqua "glorious" (WJ:412) from alcar "glory". Etymologically, -inqua means "-full", like "glory-full" in this case. A variant *-unqua is implied in WJ:415 (only referred to in archaic form -unkwā). "The forms using u were mainly applied to things heavy, clumsy, ugly or bad", whereas -inqua (in the same source derived from -inkwā) is neutral.
