ink-black

The compound 'ink-black' is a straightforward descriptive term from Modern English, combining two ancient roots to specify a precise shade. 'Ink' traces back to Greek 'enkauston', referring to a pigment 'burnt in' or fixed by heat, originally describing a prized purple ink. 'Black' originates from the Proto-Germanic 'blakaz', meaning 'burnt', a concept directly linking the color to the residue of fire. The fusion of these terms logically creates a metaphor: the color is as deeply dark as the liquid used for writing, with 'ink' intensifying the basic color denoted by 'black' to imply a pure, saturated darkness.

Structure: ink (dark liquid) + black (color) ink: From Middle English 'inke', from Old French 'enque', from Latin 'encaustum' (a kind of purple ink used by Roman emperors), from Greek 'enkauston' (burnt in, a purple ink). In this compound, it functions as a noun modifier specifying the type of black. black: From Old English 'blæc' (dark, black), from Proto-Germanic 'blakaz' (burnt). It functions as the head noun/adjective denoting the color.
