Laryngeal theory
This changed when Hittite was discovered and deciphered in the early 20th century. Hittite had a sound or sounds written with symbols from the Akkadian syllabary conventionally transcribed as ', as in ' "I put, am putting". This consonant did not appear to be clearly related to any of the consonants then reconstructed for PIE, and various unsatisfactory proposals were made to explain this consonant in terms of the PIE consonant system as it had then been reconstructed. It remained for Jerzy Kuryłowicz ("Études indoeuropéennes I," 1935) to propose that these sounds lined up with Saussure's conjectures. He suggested that the unknown consonant of Hittite was in fact a direct reflex of the "coefficients sonantiques" that Saussure had proposed.
