The second set are semantic – they deal with the set of concepts modeled by the program design.
	However, the distinction between syntactic and semantic is more organizational than formal at this point.
	The majority of Fowler’s refactorings can be restated in terms of one or more of these verbs, and the resulting verb-plus-nouns representation of design change more naturally fits into the interaction model I have proposed.
	These concepts also can apply to other programming languages, although specific meaning is language-dependent.
