意味

To conceal; to hide; to slip something somewhere secretly; to embed discreetly.

A Group 2 (ichidan) causative verb derived from 忍ぶ (to endure, to conceal). It describes the act of placing or hiding something out of sight, or subtly embedding something — an emotion, a hint — in a manner not immediately visible. Unlike 隠す (simply to hide), 忍ばせる suggests finesse and deliberateness: slipping something in without detection.
