Is the word alface the same in Brazilian and European Portuguese?

Yes

The word "alface" is identical in both Brazilian and Continental Portuguese regarding its spelling, meaning, and grammatical gender (feminine). The only difference lies in pronunciation:

• Brazilian Portuguese: The vowels are typically more open, and the final "e" is often pronounced as a subtle "i" (e.g., al-fa-si).
• Continental Portuguese: The vowels are more closed, and the final "e" is often reduced or nearly silent, making the word sound almost like it ends in an "s" (e.g., al-fas).

Brazilian Portuguese Examples

1. Eu gosto de colocar alface no meu sanduíche. (I like to put lettuce in my sandwich.)
2. A alace está bem fresquinha hoje. (The lettuce is very fresh today.)
3. Você pode comprar alface para o almoço? (Can you buy lettuce for lunch?)
4. Eu não aguento comer alface todo dia. (I can't stand eating lettuce every day.)
5. Tem alface na geladeira? (Is there lettuce in the fridge?)

Continental Portuguese Examples

1. Preciso de comprar alface ao supermercado. (I need to buy lettuce at the supermarket.)
2. Esta alface está muito fresca. (This lettuce is very fresh.)
3. Não gosto nada de alface. (I don't like lettuce at all.)
4. Põe um pouco de alface na salada, por favor. (Put a bit of lettuce in the salad, please.)
