Abstract
The aim of this article is to investigate the properties of primitive words with respect to insertion operation, called ins-primitive words. This includes the investigation of properties concerning primitive words (with respect to catenation operation) in order to show our result concerning the self-insertion of a word. We also show that the set of all ins-primitive words is not only dense but also disjunctive (hence not regular).
