جامور

Etymology
Due to the pattern occurring in Classical Arabic only in borrowings, for instance, , , , and particularly , it presupposes, as Fraenkel already explicitly noted,  and  of similar sense, but this is not attested. By conjecture only, it is possible to relate the senses within the Arabic and Aramaic root of “heating up” coals back to more general senses of “completion, fulfilment”, which further explains the background of the term, a palm attaining maturity, perhaps by man letting it grow.

Noun

 * 1) spire, height of a tower
