gelitirilirken
Gelitirilirken is not a standard Turkish lexical item. In most sources it is treated as a misspelling or misreading of the legitimate form geliştirirken, which is the adverbial clause meaning “while it is being developed/improved.” The sequence resembles Turkish morphology, but gelitirilirken does not appear as a recognized form in authoritative grammar references; correct usage uses geliştir- plus the passive marker and the temporal conjunction -ken.
Geliştirmek means to develop or improve. The passive variant is geliştir- (root) plus the passive affix -il-
Because gelitirilirken is not standard, examples are given with the correct form. For instance: Ürünün tasarım
Some writers may encounter gelitirilirken as a typographical error, a dialectal variation, or a mistranscription. The
