In this paper, a study is presented for the decipherment of the Indus Valley Script and the determining of the rendered language, termed Indus Valley Language. The study is mainly based on three pillars: the first being the pictorial similarity of the Indus Valley Script signs to other contemporary scripts, notably the Minoan scripts of Crete and Cyprus; the second being the linguistic affiliation to Sumerian and other Altaic languages; the third being a broader knowledge of Comparative Linguistics. The result finally describes an Altaic language, written with a script of 67 main syllabograms.
Kenanidis et al. (2025) studied this question.
