Editing Persian language (section)

===Syntax===
Persian adheres mainly to subject–object–verb ([[Subject–object–verb word order|SOV]]) word order. But case endings (e.g. for subject, object, etc.) expressed via suffixes may allow users to vary word order. Verbs agree with the subject in person and number. Normal declarative sentences are structured as ''(S) (PP) (O) V'': sentences have optional [[subject (grammar)|subjects]], [[prepositional phrase]]s, and [[object (grammar)|objects]] followed by a compulsory [[verb]]. If the object is specific, the object is followed by the word ''rā'' and precedes prepositional phrases: ''(S) (O + ''rā'') (PP) V''.<ref name="mahootian1997"/>
