Covered with small marks, spots or bits of something — not stripes, not big patches, but little scattered dots, as if someone had shaken a brush at it. It is usually followed by 'with': hair flecked with grey, a shirt flecked with paint, snow flecked with dirt. The spots are small and irregular and spread over the surface, and they are usually a different colour from what is underneath. Writers love this word because it is gentle; it suggests you have to look closely to see the marks. It also carries a soft feeling of time passing when used about hair or skin — 'flecked with grey' is a kinder way of saying someone is getting older. You can also say 'flecks' as a noun: flecks of gold, flecks of green in her eyes.
