domino
UK: ˈdɒmɪnəʊ | US: ˈdɑːmɪnoʊ
n. a small rectangular tile used in games, marked with dots resembling dice
n. a costume consisting of a hooded cloak and mask, worn at masquerades
n. a chain reaction where one event triggers a series of similar events (e.g., "domino effect")
The word "domino" originated in 18th-century French, derived from Latin dominus ("lord"). It initially referred to a black hooded cloak worn by priests, later adopted in masquerades. The game sense arose from the resemblance of the tiles' black dots to the cloak's pattern. The "chain reaction" meaning emerged metaphorically in the 20th century, likening sequential collapses to falling domino tiles.
