What does crumb mean?
A crumb is most familiar as the small piece of bread or cake that breaks off and scatters across a tablecloth or plate — the residue of eating that we sweep away without a second thought. Yet the word carries more weight than its size suggests. Figuratively, a crumb stands for anything tiny or barely sufficient: a crumb of comfort, a crumb of information, not a crumb of evidence. In this extended use, it often conveys scarcity or meagreness, sometimes with an undertone of condescension, as when someone offers only the smallest possible share. As a verb, to crumb means to break into fragments or, in cooking, to coat meat or vegetables in breadcrumbs before frying, giving them a crisp outer layer. Derived forms include crumbly and crumbling, describing textures that readily fall apart. An old word reaching back to Old English cruma, crumb has been part of the language for well over a thousand years, quietly serving both the kitchen and the metaphorical table.
A very small piece broken from bread, cake, or similar food; figuratively, a tiny amount or trace of something abstract.
"Not a crumb of cake remained by the time he arrived."
The figurative use often appears in the phrases 'a crumb of comfort' or 'not a crumb of evidence'.
To break something into small fragments; in cookery, to coat food with breadcrumbs.
"Crumbed fish is a favourite at the seaside café."
Standard regular plural; used both literally for fragments of food and figuratively for traces of something.
"The birds picked up the crumbs scattered on the lawn."
The word 'crumb' has been around since Old English — it was 'cruma' then, meaning the very same thing.
