IPA: /ˈθrɔːldəm/
KK: /ˈθrɔːldəm/
A condition where someone is controlled or dominated by another person, often in a way that resembles slavery or servitude.
The workers lived in thralldom, unable to escape their harsh conditions.
Thralldom is formed from "thrall" (from Old Norse *þræll*, meaning slave or servant) and "-dom" (meaning state or condition). The word refers to the state of being a thrall or in servitude.
Imagine being in a 'state' ('-dom') of servitude as a 'slave' ('thrall') — that's what thralldom means.
