TIME LIMIT is a concept that is used to refer to a specific period of time in which something must be completed. The term can be broken down into four distinct words: SETA (4 letters), CURFEW (6 letters), DEADLINE (8 letters), and HHOUR (5 letters). SETA is an acronym for 'Specific, Exact, Time Allotted', while CURFEW is a French word meaning 'to cover' or 'to protect'. DEADLINE is a combination of the words 'DEAD' and 'LINE', referring to a LINE that cannot be crossed. Finally, HHOUR stands for 'Hours of Hard Work and Urgency Required'. All of these terms are used to refer to the same concept: a limited amount of time in which something must be accomplished.
