Syntax is the grammatical arrangement or form of words in sentences according to the established rules or usage in any language.
In the Greek language, the function of words -- syntax -- is not indicated by word order in a sentence per se. For example, whereas English uses word order to differentiate between the subject, direct object and indirect object , Greek uses different endings.
Similarly, a verb's mood basically indicates its function in the sentence. For example, a Greek verb in a purpose clause must be in the subjunctive(optative) mood if the verb in the principle clause is in the present (past) tense.
Fanatical ranting is not just fine because it's eloquent. What if I ranted for the extermination of a people in an eloquent manner, would that make it fine? Rather, ranting, be it fanatical or otherwise, is fine if what is said is true and just. ---PeterD, in reply to IreneY and Annis
