There are a number of particles mentioned in the ancient Egyptian language in general and the Coptic language in particular, subject to exceptional rules in terms of uses because they were not specified by linguists. In this case, from the researcher's point of view we are talking about the so-called dual Particle of concept and use. The studies have not sufficiently covered it (from the Coptic linguistic aspect) about its nature, importance and its various linguistic uses, so this study will be unique in its form and subject. The main problem on which the research was based is to determine the use of the Particle, as the opinions of scholars were somewhat confusing, and on the basis of that, the researcher came to study the texts that were clearly exposed to this administration with all linguistic derivations, both ancient and modern, and it became clear from this and that that it is an exceptional tool in terms of derivation and use.
