Social : A different sort of collision - for trivia fans

In Spanish, the word for "the" (masculine) is "el". In Arabic, the equivalent is "el" or "al". Spain was under Artab rule for 800 years until 1492 or so, and has many Moorish names such as the river Guadalquiviir (Wab-al-Kibir), meaning The Great River. So obviously, the Spanish "el" comes from the Arabic, right? No, it comes from the Latin lle, meaning "that".

In Portuguese, the word for "the" masculine is "o", and it's the same in modern Greek. So this is probably another example of a modern European word that has come from Greek, right? No. the Portuguese also comes from Latin.

These are both examples of coincidence in language. Any others spring to mind?

I thought the technical term (I lurve technical terms) was "semantic collision" but I tried looking it up and apparently it isn't. Anybody know what the correct term is?
