"The man eats a lemon."
Translation:O homem come um limão.
Or do they both mean limes? This is a long standing mystery not helped by the similarity of the words to the English words lime and lemon.
First the words: http://lime-or-lemon.blogspot.co.uk/2011/05/lime-or-lemon.html.
Second the reality (in Rio): http://eatrio.net/2012/05/lemon-lime-confusion-in-brazil.html.
Finally the complexity. I found this comment hidden away in a blog:
"Limas" in portuguese refers to a group of citrus fruits called "limões" that come from trees called "limeiras", and include "lima espanhola", "lima almiscarada","limão-taiti", "limão-cravo", "lima cafre"(also known as Kaffir), "lima doce","lima-da-pérsia", "lima Australiana", "lima espanhola", "lima selvagem" and "lima almiscarada (also called calamondin". Of course all of these "limas" are actually what we, in English,refer to as limes and what we know as lemons are actually called "limão sicilliano". Now isn't that easy?
Aren't you glad you asked?
I can't reply directly to your 2nd comment so I'm replying to your 1st instead.
When you say you wrote "limao" but the correct answer was "lime" that sounds like you were asked to translate "limão" from Portuguese to English (because "lime" is not a Portuguese word). If you had tried "lemon" instead of "limao" you would have been correct too. I may have misunderstood what you meant though.
They are almost the same. Davu gave us a good explanation. I would like to complement that lima in portuguese has another meaning.
Lima also refers to a kind of tool commonly used in a factory or industry
Here the page in English and Portuguese of this tool
I'm sorry, it was just my idea of a joke. I'm from the UK and you're right the name we use is "nail file". Perhaps "lima de unhas" is more common in Portugal, I don't know, but even in Brazil you'll find stores selling nail files under that name, for example: http://www.esmaltrends.com.br/lixas/enox-lima-de-unhas-soft.html.
LoL. I swear that I had this impression of what you were telling was a joke.
Ohh fantastic you are from UK, I'm studying to take FCE test.
You are right, we really have some stores selling nail file, not too common, but if you ask for this in a store certainly you will find.
Living and learning. LoL
