Abstract
Since the days of classical Montague Grammar, formal semantics is frequently characterised as intensional, type-logical and model-theoretic. This paper takes a closer look of some less obvious changes these three key concepts have undergone since the appearance of English as a Formal Language. While intensions used to be crucial for resolving substitution puzzles, they are now giving way to more general constructions of index-dependant denotations. Types, on the other hand, were promoted from handy taxonomic devices to driving forces in meaning composition. Finally, the rĂ´le of models was overestimated in the early days of formal semantics, but appears to have lost its importance.
