Abstract: The object of the research is the 'I/We regret' apology speech formula. The subject of the research is the linguosemiotic characteristics thereof. The aim of the research is to define peculiarities of this speech formula, for this it is necessary to view it from the point of view of three approaches offered by liguosemiotics: semantics, syntax and pragmatics. In addition, the author has analyzed statistical characteristics of this apology formula which allows to define the basic and additional combinations. The author has applied the descriptive and component methods of linguistic analysis. First of all, the author studies vocabulary definitions, then she defines pragmatic and syntax characteristics thereof. The novelty of the research is caused by the fact that the I/We regret apology formula has never been studied taking into account its linguosemiotic characteristics. The data obtained can be used as the ground for further mathematical linguistics research, in particular, to formalize speech formulas combined with apology speech formulas using the method of mathematical statistics.
