IPA: /ˈɪn.tɚ.taɪ/
KK: /ˈɪntərtaɪ/
A connection that allows electricity to flow between two or more power systems or a structural element that ties together vertical supports in a building.
The intertie between the two power grids improved the reliability of electricity supply.
Intertie → It is formed from "inter-" (meaning between) and "tie" (from Old English "tīgan", meaning to pull or draw). The word "intertie" refers to a connection or link between two or more systems, effectively pulling them together.
Think of things being 'pulled together' ('tie') 'between' ('inter-') different systems — that's what intertie means.
