JLPT0 G13 S0 F1241

?derives from a depiction of a square jaw, taken broadly as a body part enabling the mouth to close upon and contain food (compare 頷) and thus associated with confinement. 巸 is ?(confine) + 巳 (fetus) → fetus confined in a womb. 煕 is as per 巸# (confine) + 火 fire → brilliant fire, confined to a particular place → *bright*; *shine*. *Spread* is via a Japanese reinterpretation of the character (fire spreading within a confined space), as is *abate* (← abating fire) → *relax* (← ease ← abating fire).
