Appealing is formed from "appeal" (from Old French *apeler*, meaning to call or summon) and "-ing" (a suffix used to form present participles or adjectives). The word "appealing" describes something that calls to or attracts interest or admiration.
Think of something that 'calls to you' — that's what appealing means, as it draws your attention or interest.
