high-dollar

the compound adjective 'high-dollar' is a modern american english formation that directly combines two common words to create a transparent meaning. 'high', from old english, carries its figurative sense of 'great in amount or degree'. 'dollar', entering english via dutch or low german, refers to the standard monetary unit. the term's logic is straightforward: a 'high' number of 'dollars' equates to a large sum of money. it emerged in the late 20th century, particularly in business and marketing contexts, to describe transactions, items, or clients associated with significant financial value, effectively functioning as a synonym for 'high-cost' or 'big-ticket'.

Structure: high (great in amount) + dollar (unit of currency) high (old english 'hēah', meaning of great vertical extent or great in amount); dollar (from low german 'daler', short for 'joachimstaler', a coin from the joachimstal silver mine, now a standard unit of currency).
