By 'designation', VerbaAlpina understands the idealised instance of a written, a spoken or a thought word that denotes one or several concepts and possibly references concrete things. Instead of a single word a specific sequence of several words can take over these functions (the so-called Multi-word expression). Regarding the category 'concept', a so-called m:n-relation is given speaking in terms of computer science: A polysemous designation can denote several concepts, the other way round a concept can be denoted by a multitude of synonymous designations.
