Etymology
the word 'quadruplet' is a modern formation built upon classical latin roots. the first element, 'quadru-', directly descends from the latin numeral 'quattuor' for four. the second element, '-plet', is a reduced form of '-ple', derived from latin '-plus' (meaning fold or multiple), which is related to the verb 'plicare' (to fold). this etymological construction follows a clear multiplicative logic: a 'quadruplet' is conceptually a 'four-fold' entity. while the latin root 'quadruplex' meant 'fourfold', the english suffix '-plet' was adapted in the 18th and 19th centuries, influenced by words like 'triplet' and 'duplet', to specifically denote one of a multiple birth or a grouped set.
Analysis

'quadru' is from latin 'quadru-', a combining form of 'quattuor' meaning 'four'. 'plet' is a variant of the suffix '-ple', from latin '-plus' meaning 'fold', used to form multiplicative adjectives and nouns.
