      Because real lexicons are big and complex, from a software engineering perspective it is best to write simple grammars that have a simple, well-defined way, of pulling out the information they need from vast lexicons. That is, grammars should be thought of as separate entities which can access the information contained in lexicons. We can then use specialised mechanisms for efficiently storing the lexicon and retrieving data from it.
