Natural language grammar implementations that are constructed manually can grow over time to become large, complex resources covering an ever wider range of language phenomena. It would be useful both for the grammarian and for the users of a grammar to have a good understanding of how a later version of that grammar behaves in contrast to an earlier version, particularly in terms of the treatment of linguistic phenomena. This paper presents a case study of the evolution of an implemented grammar, comparing two versions of the same grammar by measuring several properties of the analyses recorded using that grammar in two corresponding versions of an associated dynamic treebank
