IPA: /ˈɡælənɪdʒ/
KK: /ˈɡælənɪdʒ/
A measurement of volume that indicates how many gallons are present.
The gallonage of the tank is sufficient to hold all the water needed for the garden.
Gallonage → The word is formed from "gallon" (from Old French *galon*, meaning a measure of liquid) and the suffix "-age" (meaning a collection or amount). Thus, "gallonage" refers to the amount or collection of gallons.
Think of a 'gallon' as a measure of liquid, and '-age' indicating a collection or amount — that's why 'gallonage' refers to the total amount measured in gallons.
