A new resource has been created, which aims to solve illegible words in Ottoman Turkish manuscripts. It currently only explores words in Ottoman Turkish, but Arabic and Persian words will be included in the database soon. However, it can already find words in these language due to the large size of the database.
In order to find the illegible words, it is necessary to add the legible letters to the boxes and then put a * for illegible ones. It then provides a list of possible words that match the criteria, going through a list of approximately 170 thousands words. The words and phrases come from more than 15 prominent dictionaries.
