IPA: /ˈdɛtrɪmənt/
KK: /ˈdɛtrɪmənt/
Something that causes harm, damage, or loss.
The new policy was implemented without any detriment to employee morale.
Detriment is formed from "de-" (meaning down or away) and "trahere" (meaning to draw or pull). The word describes something that draws away from well-being or causes harm.
Think of something that pulls you down ('de-') and causes harm ('trahere') — that's why detriment means harm or damage.
