tengwa (pl. tengwar is attested) (1) noun "letter" Tengwa (ñ) is defined as "any one visible sign representing (theoretically) any one audible teñgwe" (phoneme) (VT39:17). In non-technical usage tengwa was equivalent to "consonant", since only the consonants were full signs (WJ:396, TEK). In the Etymologies, tengwa was apparently emended from tengwë (VT46:17).
