stipulate: [17] Tradition has it that the etymological notion underlying stipulate is an ancient custom of breaking a straw to seal a bargain. The word comes from the Latin verb stipulārī ‘bargain, demand’, and it has been speculated that this was derived from Latin stipula ‘straw’ (source also of English stubble [13]). The theory has not been conclusively demonstrated, but it makes a good story. Another possibility is some connection with Old Latin stipulus ‘firm’.
