Questions & Answers about Ellos están muy felices.
Why do we use estar instead of ser in this sentence?
Can I say Ellos son muy felices instead?
Do I always need to include Ellos?
Not necessarily. Spanish often omits subject pronouns because the verb form can make it clear who’s being talked about. So Están muy felices is also valid unless you specifically need or want to emphasize the subject Ellos.
What is the difference between muy and mucho?
Use muy to modify adjectives or other adverbs, like in muy felices (“very happy”). Use mucho to indicate quantity or to modify verbs, for example, trabajan mucho (“they work a lot”).
