Etymology
The word "twilit" is a Modern English formation, derived from the noun "twilight" by adding the suffix "-t", a variant of the past participle ending "-ed". "twilight" itself originates from Old English "twēonelēoht", a compound of "twēone" (meaning 'two' or 'double/doubtful') and "lēoht" (light). This ancient sense of "doubtful light" or "light between two states" perfectly captures the ambiguous, intermediate illumination of dusk or dawn. The adjective "twilit" thus poetically describes a scene or atmosphere bathed in this soft, fading, and ambiguous light, directly inheriting the core semantic concept from its parent noun.
Analysis
This is a simplex word formed by derivation from the noun "twilight" with the addition of the past participle suffix "-t".
