IPA: /ˈliːkɪdʒ/

The amount or process of something escaping or being lost due to a leak.

Leakage → It is formed from "leak" (from Old English *leacian*, meaning to flow or escape) and "-age" (a suffix indicating a process or result). The word "leakage" refers to the process or result of something flowing or escaping, typically a liquid or gas.
Think of something that is 'flowing out' ('leak') as a process or result ('-age') — that's what leakage means.
