IPA: /ˈθrɒtəlhoʊld/
KK: /ˈθrɑːtəlhoʊld/
A strong and often oppressive control or influence over someone or something, similar to a stranglehold.
The company's throttlehold on the market made it difficult for new competitors to enter.
Throttlehold → It is formed from "throttle" (from Old English *þrotl*, meaning to strangle or choke) and "hold" (from Old English *healdan*, meaning to keep or grasp). The word "throttlehold" refers to a grip that restricts or chokes, often used in a figurative sense to describe control or dominance over someone or something.
Imagine a grip that 'chokes' ('throttle') and 'keeps' ('hold') something tightly — that's why a throttlehold means a strong, controlling grip.
