A grammar is essentially noncontracting if there may be one exception, namely, a ruleS → εwhere S is the start symbol and ε the empty string, and furthermore, S never occurs in the right-hand side of any rule.None of the rules of a noncontracting grammar decreases the length of the string that is being rewritten. If each rule even properly increases the length, the grammar is called a growing context-sensitive grammar."@en }
