blank

The word 'blank' traces its lineage to the Proto-Germanic adjective blankaz, meaning "bright, white, shining." This term passed into Old French as 'blanc,' retaining the sense of the color white. In Middle English, the word was borrowed from French with the spelling 'blank,' initially describing the pale, unmarked quality of white paper or an empty space. Over time, the meaning expanded metaphorically from a literal lack of marks or color to encompass any absence—be it of writing, decoration, expression, or thought—giving us the modern abstract senses of emptiness and vacancy.

The word 'blank' is a simplex word of Germanic origin. It entered English from Old French 'blanc' (white, shining), which itself came from a Proto-Germanic source blankaz (bright, white, shining). The core morpheme 'blank' functions as a complete lexical unit.
