The usual word for “and” in the 1910s was ᴱQ. ya(n) (PE15/69, VT40/8). It was derived from the early root ᴱ√YA (or possibly ᴱ√(D)YṆTṆ) in the Qenya Lexicon of the 1910s (QL/104-105). In his later writings, the usual word for “and” was Q. ar, but something like ya(n) survived in the “dual” conjunction yo “both ... and”.

A noun given as {āra >>} àra in the Qenya Lexicon of the 1910s glossed “dry sand, grit” given as a derivative of ᴱ√ARA “be dry” (QL/32), also mentioned as āra in contemporaneous Gnomish Lexicon alongside its Gnomish cognate G. ôr of similar meaning (GL/62). It is not clear what (if any) significance the grave accent à has.
