I want to prepare a dictionary(English to Turkish) consisting of example sentences And for a list of English words, I use "Oxford Dictionary of Current English". Is the alphabetical word order subject to copyright? ( ı will not use definitions of words)
Alphabetical order is a "fact", not an "expression" so it is not subject to copyright. For the Latin alphabet, order was established millenia ago. It is unclear who established current Turkish alphabetical order for ç, ğ, ı, ö, ş, ü, but it was probably an official government decision, and under At. 31 of Turkish copyright law, "Duplication, dissemination, adaptation or otherwise use of the laws, rules, regulations, notifications, circular letters and juridical decisions which are officially promulgated or announced is free"
