✕Common Mistakes
Quanto água eu preciso?
‘Quanto’ is masculine; with the feminine noun ‘água’ you must use ‘quanta’.
Quanta água eu preciso de?
When the verb ‘precisar’ is followed directly by the object, the preposition ‘de’ is omitted in this construction.
Quanta agua eu preciso?
Missing the acute accent changes the word to ‘agua’, which is a spelling error in Portuguese.

Cultural Tip
Portuguese speakers always use the metric system, so water is measured in litros (liters) or mililitros. In Brazil, it’s common to hear ‘um copo de água’ (a glass of water) in everyday conversation, while in Portugal people may refer to ‘um litro de água’ for larger quantities. Remember that ‘água’ is feminine, so the correct interrogative form is ‘quanta’, not ‘quanto’. Also, the verb ‘precisar’ does not require the preposition ‘de’ when the object follows directly, unlike English ‘need of’.
