IPA: //sʌbˈrɛpʃən//
KK: /sʌbˈrɛpʃən/
A deliberate act of misrepresenting information by hiding the truth or important facts.
The lawyer accused the defendant of subreption in his testimony, claiming he concealed key evidence.
Subreption is formed from "sub-" (meaning under) and "reptio" (from "reptio", meaning to seize or take). The word refers to the act of seizing or taking something under false pretenses or deceitfully.
Think of something being taken 'under' ('sub-') false pretenses — that's what subreption means.
