toll-free
UK: ˈtəʊl friː | US: ˈtoʊl friː
adj. not subject to a charge or fee
adj. (of a phone call) charged to the receiver rather than the caller
The word combines "toll," derived from Old English toll (a tax or fee, from Latin telonium via Germanic roots), with "free," from Old English frēo (exempt from obligation). Historically, "toll" referred to payments for bridges or roads, while "free" denoted exemption. By the 20th century, "toll-free" emerged in telecommunications to describe calls where the recipient bears the cost, leveraging the original sense of "free from toll."
