What is the meaning of the name Alastor ?

The baby name Alastor is a Male name , 3 syllables long and is pronounced /əˈlæstər/ (uh-LAS-ter).

Alastor is Greek in Origin.

Alastor comes from Ancient Greek Ἀλάστωρ (Alástōr), an epithet meaning “avenger” or “the unforgetting one,” applied to avenging spirits and to Zeus as punisher of moral transgression. It is analyzed as a- “not” + lanthánō “forget/escape notice,” yielding a figure who does not forget wrongs - hence a relentless avenger. Latin preserved Alastor, and the word entered English via classical literature, where it could also denote a baleful genius.

As a given name it has been rare yet resonant: Milton and Shelley used it (Shelley’s 1816 Alastor), and modern fantasy revived it, notably Alastor “Mad‑Eye” Moody. Variants include scholarly transliterations Alástōr and Alastôr; the standard English form is Alastor. Despite the similar sound, it is unrelated to Alastair/Alasdair, which come from Alexander. Core meaning: avenger, retribution, memory of wrongs - lending the name a dark, mythic gravitas for parents seeking an archaic, striking choice.
