Task: Text Categorization
Input (English): Ishmael Reed used a concept from this mans theories to title a chapter of his Mumbo Jumbo, which used that theory to discuss blackness. He wrote extensive unpublished notes detailing a theory of Latin poetry that centered on anagrams. His most prolific work contrasts synchronic study, which has no concept of time, and diachronic study, which outlines evolution over time. He theorized an arbitrary sign characterized by a signifier and a signified. An unpublished manuscript of this man was found in 1996 and published as Writings in General Linguistics, and he outlined the laryngeal theory in his Thesis on the Primitive Vowel System in Indo-European Languages. For ten points, name this linguist whose Course in General Linguistics was developed from notes on his lectures.
Output (English): Social Science
