Mladih
Mladih is a grammatical form used in several South Slavic languages to express the concept of “of the young.” It is the genitive plural form of the adjective mlad (meaning young). In standard orthography, the form is typically written as mlađih with the diacritic đ; in ASCII transliteration it appears as mladih. The form is used to modify masculine, feminine, or neuter nouns in the genitive plural.
In practice, mladih appears in phrases that denote a subset or characteristic group of people or things
Etymologically, mlad comes from Proto-Slavic roots meaning “young,” and mlađi or mladih are its inflected forms
