A — 1: ἐξουσία
(Strong's #1849 — Noun Feminine — exousia — ex-oo-see'-ah )

denotes "authority" (from the impersonal verb exesti, "it is lawful"). From the meaning of "leave or permission," or liberty of doing as one pleases, it passed to that of "the ability or strength with which one is endued," then to that of the "power of authority," the right to exercise power, e.g., Matthew 9:6; 21:23; 2—Corinthians 10:8; or "the power of rule or government," the power of one whose will and commands must be obeyed by others, e.g., Matthew 28:18; John 17:2; Jude 1:25; Revelation 12:10; 17:13; more specifically of apostolic "authority," 2—Corinthians 10:8; 13:10; the "power" of judicial decision, John 19:10; of "managing domestic affairs," Mark 13:34 . By metonymy, or name-change (the substitution of a suggestive word for the name of the thing meant), it stands for "that which is subject to authority or rule," Luke 4:6 (RV, "authority," for the AV "power"); or, as with the English "authority," "one who possesses authority, a ruler, magistrate," Romans 13:1-3; Luke 12:11; Titus 3:1; or "a spiritual potentate," e.g., Ephesians 3:10; 6:12; Colossians 1:16; 2:10,15; 1—Peter 3:22 . The RV usually translates it "authority."

B — 3: αὐθεντέω
(Strong's #831 — Verb — authenteo — ow-then-teh'-o )

from autos, "self," and a lost noun hentes, probably signifying working (Eng., "authentic"), "to execise authority on one's own account, to domineer over," is used in 1—Timothy 2:12 , AV, "to usurp authority," RV, "to have dominion." In the earlier usage of the word it signified one who with his own hand killed either others or himself. Later it came to denote one who acts on his own "authority;" hence, "to exercise authority, dominion." See DOMINION , Note.
