In linguistics an
accidental gap, also known as a
gap or
a hole in the pattern, is a word or other form that does not exist in some language but which would be expected to exist given the grammatical rules of the language.[1] For example, in English a noun may be formed by adding the suffix -al to a verb (e.g. recite → recital; arrive → arrival), yet there is no English word describal related to the verb describe.[2] Although theoretically such a word could exist, it does not;
its absence is therefore an accidental gap.
