Synonym discussion
Sense: noun/1
Semi-darkness describes a condition where some light remains but not enough to see clearly — it is a neutral, descriptive term. Gloom adds a mood of sadness or depression to the low light, as in 'the gloom of a rainy afternoon'. Dimness focuses specifically on the weakness of the light source itself rather than the overall scene. Twilight is tied to a specific time of day (sunrise or sunset) and has a poetic or romantic tone. Darkness is the most common word and describes the complete absence of light — a stronger condition than semi-darkness. In writing, 'the semi-darkness of the attic' suggests you could still see shapes, while 'the darkness of the attic' suggests you could see nothing at all.

Etymology
Formed by combining the prefix 'semi-' (meaning 'half' or 'partially', from Latin) with 'darkness' (from Old English 'deorc' meaning 'without light' + the noun suffix '-ness'). The word entered English as a compound to describe conditions that fall between light and total darkness.
