IPA: /ˈdɛtɪnjuː/
KK: /dɛtɪnju/
A legal term referring to the act of unlawfully keeping someone else's personal property or the action taken to recover that property.
The company filed a detinue to reclaim the equipment that was wrongfully held by the contractor.
Detinue is derived from the Latin "detinere" (meaning to hold back or retain), which is composed of "de-" (meaning down or away) and "tenere" (meaning to hold). The word refers to the act of holding back or retaining someone's property.
Think of 'holding back' ('tenere') something 'away' ('de-') — that's why detinue means to retain someone's property.
