This document discusses time as a linguistic concept in ancient Egyptian, specifically examining whether there was an interrogative word for "when". It analyzes sources from different time periods and genres. While words existed for other interrogatives like "what", "who", "why", and "where", the analysis found no examples of an interrogative word for "when" in Late Egyptian texts, though Middle Egyptian examples use "at what time". The document concludes there may have been a missing linguistic category for interrogating time in ancient Egyptian language.
