Pattern

Abstract

The word “pattern” is a very complex term. Generally, it refers to “an arrange- ment that reveals an order, or design, which is meaningful” (cf. Thaker 1999: 427). But a quick look at many of its different domains of application (e.g. theoretical biology, mathematics, aesthetics, linguistics, etc., etc.) proves that “pattern” has a semantic potential richer than one usually expressed by such a definition. For instance, in the framework of the so-called combinatorics on words (cf. at least Lothaire 2012), a pattern is “a word over an alphabet of variables and is meant to describe some kind of repetitive structures” (cf. Rampersard 2017: 98). Therefore, in this first theoretical approach, “the pattern XX over the single variable X is meant to describe the repetition of the same word twice in succession” (cf. Rampersard 2017: 98).
