abalienate comes from Latin abaliēnātus, past participle of abaliēnāre ('to separate, transfer, estrange'), from ab- ('away from') + aliēnāre ('to make another's'), from aliēnus ('belonging to another'), from alius ('other'). Morphologically, the word is transparent as a compound: its parts remain visible in the modern spelling, while the older history of those parts supplies the deeper ancestry. In modern use, the verb sense is "to transfer ownership of property to another, especially by legal conveyance", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as alienate, alien, alienation and derivatives such as abalienation, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin abaliēnāre, Latin alius, Proto-Indo-European *h₂el-, which anchor the explanation in named linguistic material.
