Word order is how the words in the sentence join together to make a sentence

In English the word order is S V O.

The S stands for subject (Pronouns). You, we, e.t.c.

The V stands for Verb/Action. Run, loves, e.t.c.

The O stands for object/predicate. In most languages the object is optional in a sentence. For example if I say 'I run' there is a subject and a verb but no object. 'I love her' has all three elements, 'I' is a subject, 'love' is the verb and 'her' is the object.

Direct Object Entirely acted upon. John fed the DOG.
Indirect Object Entity indirectly affected by the action Johnny loves HER.
Prepositional object Object introduced by a preposition She is looking for JOHNNY.
