1 A – alpha, the first letter of the Greek alphabet. 1/a (alpha) is used as a prefix (called its "privative use") and typically means "no" or "not" (= "un-," "without").

[Greek words, whose first letter (of the root) is alpha, can not take an "alpha-privative" to negate them, so the only way to express their "antithesis" is using a negative particle before them (e.g. mē, ou).]

Example: There is no single word for "unforgiveness" in the NT because the first letter is already alpha ("a") – so a negative has to be used separately like, "not forgive" (ou/mē aphiēmi). "Righteousness/judge" (dikē) however does not begin in Greek with the letter "a" so unrighteousness is formed by using the prefix alpha (adikia).

Of Hebrew origin; the first letter of the alphabet; figuratively, only (from its use as a numeral) the first: --Alpha. Often used (usually an, before a vowel) also in composition (as a contraction from aneu) in the sense of privation; so, in many words, beginning with this letter; occasionally in the sense of union (as a contraction of hama).
