It is true that no one would call it almost Semitic, but some very common words are of arabic origin.

Taza, guitarra, almohada, albañil, algebra, elíxir, tamarindo, fulano, alfombra, acimut, cenit, café, azúcar, naranja, azar, ajedrez, arsenal, aceite, alcohol, arroba, azulejo, alberca, cero, etc.

And also several toponyms, the most famous probably being Andalucía.

Several of the words you list are also English words: guitar, algebra, elixir, tamarind, cafe, orange, arsenal, alcohol. When talking about English origins do we count those for Spanish or Arabic? ;)

Only guitar in that list comes to English from a Spanish etymology, the others come from Arabic via medieval Latin, French and Italian, not Spanish.

azimuth, zenith

Andalucía to name the geography is Arabic-speakers’ legacy, but as a term for a people, it can be traced further back to a Germanic root.
