I am trying to understand the etymology of the Sicilian word "sceccu", which means "burro". Some common explanations for its etymology are that it derives from Turkish eşek ("donkey") or Arabic شيخ ("sheikh"), but I don't find these satisfactory and suspect it has a different origin.
I found some similar looking words with the same meaning in some western romance languages:
- "jegue" (Portuguese)
- "jeque" (Old Provençal)
Does a similar word exist in Spanish, and if so, what is its etymology?
I guess that "equus" is involved, but I don't understand the j-x-sh at the beginning.
