the.com/transmission tower
a steel giant holding the sky's electricity so it never has to touch the ground.
means A tall steel structure, usually a lattice frame, that supports high-voltage power lines and keeps them safely elevated above the ground.
from A plain compound of two Latin-rooted English words. "Transmission" comes from Latin transmittere, "to send across" (trans-, "across," plus mittere, "to send")—the same root that gives us "missile" and "mission." "Tower" descends from Latin turris, a tall structure, borrowed through Old French into English long ago. The pairing is modern, born with the electrical grid: once electricity had to be "sent across" great distances at high voltage, engineers needed turris-like steel giants to carry it—and so the transmission tower got its workmanlike name.
