NŌ also / también, conjunción y (M) This particle bonds with others in various clusters incorporating the sense of 'also,' but there appears to be another clitic NO with a short vowel, which is a component of NOCEH 'or else,' NOZO 'either.’ AHNOZO ‘or, perhaps’ and NOZAN 'still, up until now.' In these the vowel of NO is specifically marked short or left unmarked for length; it is never marked long. This is abundantly attested in B and C and also appears in R and X but not at all in T and Z. NO See NŌ.
