Monarch and Sovereign
monarch is derived from the Greek μονάρχης, monárkhēs, "sole ruler" (from μόνος, mónos, "single" or "sole", and ἄρχων, árkhōn, archon, "leader", "ruler", "chief", the word being the present participle of the verb ἄρχειν, árkhein, "to rule", "to lead", this from the noun ὰρχή, arkhē, "beginning", "authority", "principle") through the Latinized form monarcha.
The word sovereign is derived from the Latin above.
Autocrat is derived from the Greek αὐτοκράτωρ: αὐτός ("self") and κρατείν ("to hold power"), and may be translated as "one who rules by himself".
