IPA: /ˈtaɪtˌroʊp/
KK: /ˈtaɪtˌroʊp/
A rope or wire that is stretched tightly, used by acrobats to walk or perform high above the ground.
The acrobat skillfully walked across the tightrope without losing balance.
Tightrope → It is formed from "tight" (from Old English *tihht*, meaning firmly held or secure) and "rope" (from Old English *roppa*, meaning a cord or string). The word "tightrope" refers to a rope that is held firmly, typically used in acrobatics for walking across it.
Think of a rope that is held 'firmly' ('tight') — that's why a tightrope is a rope that is tightly secured.
