			==Formal definition==
			A prefix grammar ''G'' is a [[n-tuple\|3-tuple]], (Σ, ''S'', ''P''), where
			*Σ is a finite alphabet
			*''S'' is a finite set of base strings over Σ
			*''P'' is a set of production rules of the form ''u'' → ''v'' where ''u'' and ''v'' are strings over Σ

			For strings ''x'', ''y'', we write ''x →<sub>G</sub> y'' (and say: ''G'' can derive ''y'' from ''x'' in one step) if there are strings ''u, v, w'' such that ''x = vu, y = wu'', and ''v → w'' is in ''P''. Note that ''→<sub>G</sub>'' is a [[binary relation]] on the strings of Σ.

			The ''language'' of ''G'', denoted ''L(G)'', is the set of strings derivable from ''S'' in zero or more steps: formally, the set of strings ''w'' such that for some ''s'' in ''S'', ''s R w'', where ''R'' is the [[transitive closure]] of ''→<sub>G</sub>''.

			==Example==
			The prefix grammar
			*Σ = {0, 1}
			*''S'' = {01, 10}
			*''P'' = {0 → 010, 10 → 100}
			describes the language defined by the [[regular expression]]
