A derivation of a sentence of a grammar is, in effect, a proof that the sentence can be derived from the start symbol of the grammar using the grammar rules and a rewriting process For example, given the grammar 1 S -> NP VP, 2 NP -> ART N, 3 VP -> V, and lexical rules 4 ART -> "the", 5 N -> "cat", and 6 V -> "miaowed", we can derive the sentence "the cat miaowed" as follows: S=>NP VPrule 1 =>ART N VPrule 2 =>the N VPrule 4 =>the cat VPrule 5 =>the cat Vrule 3 =>the cat miaowedrule 6 One can then write S =>* "the cat miaowed": i e =>* is the symbol for the derivation relation The symbol => is referred to as direct derivation
a line of reasoning that shows how a conclusion follows logically from accepted propositions
The process of making a new class based on an already existing class The only way to use an abstract class is to make a derivative concrete class
in this process affixes and the basic form are combined to create new words à un - known

A finite, non-empty sequence of wffs in which the last member is the wff derived, and each of the others (the premises) is either an axiom, a member of a set of accepted premises, or the result of applying a rule of inference to wffs preceding it in the sequence See corresponding argument; proof Notation: A (the wff A can be derived from the set of wffs )
characterized by inflections indicating a semantic relation between a word and its base; "the morphological relation between `sing' and `singer' and `song' is derivational"
