For why would the scribe in Beirut think it useful to gloss the logogram SAHAR with the Canaanite word 'aparu
unless he thought that the scribe who read his letter needed the word for "dust" in Canaanite in order to interpret the logogram for "dust" in cuneiform?
It is unclear how best to interpret the connection between the West Semitic words built from *[square root of ([gamma]pr)] and the Akkadian terms upru "a type of headdress" and aparu
"to provide a headdress." The voweling of eriptum is consistent with an earlier *[gamma]iprtum, whereas that of aparu
(rather than *eperu) is difficult to reconcile with the presence of an original *[gamma].
