1 prefix "up" AMsup2/sup
2 prefix used in comparison, signifying addition, increase PE17:90, or with genitive superlative: elenion ancalima brightest of stars PE17:91. Originally identical with \#1 above. The form am- as such is in late Quenya only used before p and presumably before vowels; the longer form ama- came to be preferred before r and l; before other consonants, the prefix assumes the form an- pronounced, but not in Romanized Quenya orthography written, añ- before c PE17:90-92. Phonologically we would expect am- before y- since my is an acceptable Quenya combination; however, Tolkien used an- in the word anyára q.v. See an- \#2 and compare ar- \#2.
