Excalibur Sword of Ali
Ex — Calib — eR:
In arabic the root word Calib means heart. The Ex- and -eR would have been added when the word was borrowed, and the -er or -re suffix is the active participle (of English and French grammar).
The word calibrate stems from qalb, in this case the heartbeat was used to measure time.
The word calibre also orginates from the arabic root word for heart قلب qalb. qalib قالب means mould, template, form, matrix, model, measure or standard, it is the likely origin for the word calibre.
If the name Excalibur is of arabic origin then it should have a similar meaning to the word calibre (a standard or measure), a better standard of sword.
Excalibur might simply be a transliteration of the Allah-ho-Akbar.
That’s an interesting connection, because calibre is used to categorize the size and length of a weapon, for example a gun.
It is not just the name of Excalibur that may be middle-eastern, but the legend of King Arthur too. The written versions of King Arthurs stories coincide with the Norman campaigns against the muslims in Portugal and the crusades in Palestine. Trading routes might have brought the stories of Arthur (Atharاثار) to Britain and France even earlier.
