In this lesson, we’ll take a look at the last subset of quantifiers: interrogative quantifiers. Interrogative quantifiers (quantificadores interrogativos) introduce questions about quantities. A question using an interrogative quantifier is invariably answered using another quantifier.
Quanto, Quanta, Quantos, Quantas
Remember these? Quanto (masculine) and quanta (feminine) are singular forms equivalents to “how much” in English. Examples:
Quanto gastaste ontem? How much did you spend yesterday?
É precisa quanta lã para umas luvas? How much wool is needed for a pair of gloves?
Quantos and quantas are the plural forms of quanto and quanta, and they’re equivalent to “how many” in English. Examples:
Quantos amigos teus convidaste? How many of your friends did you invite?
São necessárias quantas folhas? How many sheets are needed?
As stated, an interrogative quantifier is always answered with another quantifier. Example:
Quantos pãezinhos quer? How many rolls would you like?
Queria cinco, por favor. I’d like five, please.
