👉 Resolvability is a concept in mathematics that refers to a property of a formal language, where it is impossible to define or express every word using only finite symbols. This means that there are words which cannot be expressed as a finite number of strings, even if the alphabet used is infinite. Resolvability can be seen as an important aspect of computability theory and is related to the study of the definability of certain types of expressions in formal languages. In other words, for any language L
