What other languages influenced Greek?

In terms of the usual interpretation of the question (what languages did Greek borrow words from), at different times Greek has borrowed words from:

• Persian (a small number)
• Latin (a fair few)
• Slavonic (surprisingly few)
• Albanian (surprisingly fewer)
• Aromanian (ditto)
• Catalan (one word, παρέα < pare(j)a)
• Romany (very few, although it is the go-to source for cants (secrecy languages), including Kaliarda, the gay cant: Roz Mov – Kaliarda
• Old French (Cypriot)
• Italian and Venetian (lots, though they have been purged)
• (Ottoman) Turkish (lots, though they have been substantially purged)
• French (before World War II)
• English (after World War II)
• … oh, and Ancient Greek
• Can’t think of any words from Aromanian, but there should be a couple

Dialects outside of Greece have borrowed from the majority languages: Calabrian and Salentino in Southern Italy, French in Corsica, Russian and Tatar in Eastern Ukraine (formerly Crimea). And of course languages in the diaspora do the same.
