ismétldését
Ismétldését is a Hungarian noun form that denotes the act of repeating something and is used as a definite object in a sentence. In standard modern Hungarian, the common noun for this idea is ismétlés; the usual definite-object form is ismétlését. The form ismétldését is rarely attested in contemporary texts and is generally considered nonstandard, dialectal, or a misspelling of ismétlését. It may appear in older writings or regional varieties, but it is not part of the standard language.
The theoretical basis for ismétldését would involve the verb root ismétl- (from ismétel, to repeat) combined
Because ismétldését is not part of standard usage, most writers and editors would replace it with ismétlését
