platelet
UK: ˈpleɪtlət | US: ˈpleɪtlət
n. a small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting.
The word "platelet" combines "plate," derived from Old French plate (meaning "flat sheet," from Latin plattus), with the diminutive suffix "-let" (from Old French -elet). The term reflects the cell's flat, disk-like shape and its small size. Historically, platelets were observed under microscopes as tiny "plates" in blood, leading to this logical naming.
Platelets are essential for wound healing and blood clot formation.
A low platelet count can lead to excessive bleeding.
