For once, EP Word of the Week plays it completely straight with a word; [o] ice tea means exactly what you’d expect it to be: iced tea!
It’s simply another example of an English borrowing that stuck in Portugal, so much so that the actual Portuguese words for ice[d] tea, [o] chá gelado, are almost never used when one is talking about mass brand ice tea.
But as always, there’s a lesson to be learned here: if you look closely, you’ll notice that the masculine gender of the Portuguese word for tea ([o] chá) helps explain why [o] ice tea is masculine in Portuguese.
When you find yourself in Portugal, you won’t need to worry about English if you’re requesting this sweet, cold beverage! There’s still the other 95-98% of the language to master, but it’s always good to be a freebie every now and then!
