This chapter describes some of the semi-productive derivational morphological processes and the formation of some phrases doing the work of single lexical items in Panjabi. 17.1 Some productive tendencies in Panjabi deriva-tional morphology

Chapter 4 mentions two types of morphological processes – the inflectional and the derivational. When a lexeme (or dictionary word) is inflected, the result is a different grammatical form of the same lexeme. But the process of derivation creates a different lexeme. For example, we can inflect the verb create to derive its past tense form created and the present participle form creating. But we can also derive the adjective creative from the verb create. From the adjective creative, we can derive the abstract noun creativity. Creative and creativity are different lexemes ultimately derived from create. Every English grammarian would agree that created is simply a past tense form of the lexeme create, and not a different lexeme. But what about the cases involving suppletion, like went being the past tense form of go? A surviving form of an extinct lexeme has become the past tense form of go. A morphological process changes the form of a lexeme. But, strictly speaking, suppletion is not a morphological process.
