In Spanish, all you need is a subject and a verb. The subject is the person or object that performs the action of the verb, which is generally an action word conjugated in the correct form to match up with the subject.

Like in English, a very common word order in Spanish is Subject + Verb + (rest of sentence), such as in the examples below:

Structure: Subject + Verb + rest of sentence
English: Pedro + works + in the library.
Spanish: Pedro + trabaja + en la biblioteca.
However, Spanish is much more flexible in word order than English, in that the same sentence can be arranged numerous ways, even though their translation in English sounds awkward.
