Although there are thousands of programming languages, many ofthem share common features. This paper reviews some keyunderlying language concepts and the challenges they present tothe task of formal se-mantic description. Most material concernsthe responses in operational, axiomatic and denotationalapproaches to the description of programming languages. Thereare interesting overlaps between the responses of these mainapproaches to the challenges posed by the language concepts:these similarities are exposed even where accidental details oftendisguise them; essential differences are also pinpointed.
