Questions & Answers about Este aluno é muito inteligente e trabalhador.
If the student was female, would muito change to muita?
No, because here muito means 'very' and modifies the adjectives. When used as an adverb of degree like this, it never changes its form. It would still be muito inteligente for a female student (esta aluna).
Why do we use é here instead of está?
Why doesn't the word inteligente end in -o to match the masculine aluno?
Not all adjectives end in -o or -a. Adjectives that end in -e, like inteligente, usually only have one form, meaning they stay exactly the same for both masculine and feminine nouns.
What would the word trabalhador look like if we were talking about a female student?
It would become trabalhadora. Adjectives that end in a consonant like -r usually form the feminine by adding an -a at the end.
