In Spanish the order of the words in a sentence is quite flexible. However the normal order in a declarative sentence (statement) is:
Subjetc (who do the action) + Predicate (the action) + Object (who receive the action)
The subject comes first, but when it is a personal pronoun as a subject, usually is not express and it is indicated by the verb ending.
Example: (Yo) hablo francés.
The predicate is composed at least by one verb expressing the action and often by an object, or adverbs.
Example: (Tú) comes mucho.
(tú) francés? / ¿Es usted francés?
¿Habla usted italiano?
¿Por qué no come usted un poco más?
In Spanish normally in an interrogative sentence the order of the subject and verb is reversed:
