In which sentence is QUICK used correctly? -He went to the restroom real quick. -She had a quick breakfast. -He needs to study quick for the exam.
-She had a quick breakfast. Quick is an adjective in this case. In the other two instances, the right option would have been QUICKLY which is an adverb (describes how the action is done) and not an adjective.
How do I know if a noun is masculine or feminine?
Something easy you can do is to look at the articles and adjective. Spanish needs gender and number agreement, therefore the combination of article+noun+adjective will agree with the gender and number. "La casa es bella" is feminine because La is a feminine article and Bella ends in A. On the other hand, "El carro es bello" is masculine and it's obvious from El which is a masculine article and Bello ends in O.
How do I know if in the "Passato Prossimo" tense I have to choose Essere or Avere as auxiliary verb? For example, "sono andato" o "ho andato"?
A little trick you can use that works 99% of the time is this: if the verb is transitive (verb that requires a direct object, indicating the person or thing that receives the action of the verb) then the auxiliary is "Avere". On the other hand, if the verb is intransitive (action not done to someone or something) then the auxiliary will be "Essere", "Andare" is intransitive, so the answer is "Sono andato/a" (remember the gender agreement!). On the other hand, "Vedere" is transitive so you say "Ho visto" (no gender agreement required!)
