Milk – la leche
(Pronounced leh-che)
To remember that milk is pronounced leh-che (leche) in Spanish, use the following mnemonic:
It's a "Trust the customer Milk Bar" – you take your drink then lay some change (leche) on the bar.
Leche is feminine, so it's la leche. Imagine a lady having a bath in milk as Cleopatra did.
