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

Yes

The differences in the word "salada" between Brazilian and Continental Portuguese are limited to pronunciation.

In most regions of Brazil (particularly in Rio de Janeiro and São Paulo), the letter d is pronounced as a palatal affricate /dʒ/, sounding similar to the "j" in the English word "juice." In Continental Portuguese, the d is dental, meaning the tongue touches the teeth, resulting in a harder "d" sound. Additionally, Brazilian Portuguese tends to have more open and clearly articulated vowels, whereas Continental Portuguese often features more closed or reduced vowel sounds.

Brazilian Portuguese Examples

2. A salada de frutas está deliciosa. (The fruit salad is delicious.)
3. Você quer uma salada de maionese? (Do you want a potato salad?)
4. Eu vou preparar uma salada de alface e tomate. (I am going to prepare a lettuce and tomato salad.)
5. Essa salada está muito temperada. (This salad is very well seasoned.)
