IPA: /ˈlɪpəˌɡræm/
KK: /ˈlɪpəˌɡræm/
A type of writing or word that deliberately leaves out one or more letters or symbols.
The author created a lipogram by writing a novel without using the letter 'e'.
Lipogram → It is formed from "leipo" (λείπω) (meaning to leave out) and "gramma" (γράμμα) (meaning letter or written character). A lipogram is a piece of writing in which a particular letter is intentionally omitted.
Think of 'leaving out' ('leipo') a specific 'letter' ('gramma') when writing — that's what a lipogram is.
