overhead
UK: ˌəʊvəˈhɛd | US: ˌoʊvərˈhɛd
adj. located or operating above the head or at a height
n. the general, fixed costs of running a business (e.g., rent, utilities)
adv. above the head; in the sky
The word combines "over" (Old English ofer, meaning "above") and "head" (Old English hēafod, referring to the physical head or top). Originally literal (e.g., "overhead beams"), it later expanded metaphorically to business costs (early 20th century), implying expenses "hovering above" daily operations. The morphemes retain clear boundaries in spelling and meaning.

Office overhead includes electricity and internet bills.

The company reduced overhead by switching to remote work.
Birds circled overhead, scanning for prey.
