The Italian word 'questo' is a demonstrative adjective and pronoun that is used to indicate something close to the speaker. It translates to 'this' in English, and can refer to things, people, or ideas. It changes form based on gender and number: 'questo' (this, masculine singular), 'questa' (this, feminine singular), 'questi' (these, masculine plural), 'queste' (these, feminine plural).
This is my book
This phrase is a basic declarative sentence in Italian. 'Questo' is a demonstrative adjective used to indicate a specific object or person close to the speaker, in this case, a book. In Italian, the subject often comes before the verb, and possessive adjectives come before the noun they refer to. Hence, 'Questo' (This) comes before 'è' (is), 'il mio' (my) precedes 'libro' (book).
This food is delicious
This is a statement expressing an opinion about the quality of the food. 'Questo' is the demonstrative adjective indicating that the food is close to the speaker. 'Cibo' means food, 'è' is the verb 'to be' and 'delizioso' is an adjective describing the food as delicious.
Have you seen this movie?
This is a question seeking to find out if the person being addressed has seen a particular movie. The phrase uses the verb 'Hai visto' (have you seen), the demonstrative adjective 'Questo' (this), and 'film?' (movie). In Italian, the word order for questions is usually subject-verb-object, the same as in English. Although the subject pronoun 'tu' (you) is omitted in this context, it is implicitly understood.
