The Chinese word "十四" (shísì), meaning "fourteen", is formed through a logical, additive numerical system based on the base-ten principle. It directly combines the character for ten, "十" (shí), with the character for four, "四" (sì), to literally express "ten-four" or ten plus four. This structure is consistent for numbers 11 through 19, where the decade value precedes the unit value, showcasing a clear and systematic method of compound word formation in Mandarin numerals.
