Key Words • Inflectional Morphology: The modification of a word to fit its grammatical role. For example, 'sang' and 'walked' are inflected in the past tense. • Derivational Morphology: The creation of new words. For example, the nouns 'solemnity' and 'toughness' are derived from the adjectives solemn and tough • Virtuous Error: A mistake that is logical and sheds light on a child’s language development.
What is Morphology? • The study of word structure, especially in terms of morphemes. • Morphology is an aspect of grammar that becomes increasingly important as a child’s language develops.
Making words do different things – Inflective Morphology How many morphemes? What do the bound morphemes do? • I walked • He has two dogs • I am eating • I am the tallest person in my class • He used the steamer to cook lunch • The doctor’s surgery
Making words do different things – Inflective Morphology • I walk + ed – Shows the past tense • He has two dog + s – Plural • I am eat + ing – Progressive aspect • I am the tall + estperson in my class – Comparative • He used the steam + er to cook lunch – object performing verb • The doctor + s surgery - Possession

A Quick Recap... What do these key terms mean? Morphology: Inflectional Morphology: Virtuous Error:
Overgeneralisation • Children start to apply rules that they have observed in other people’s language. If a child has heard –ed used when talking about events that occurred in the past, they might start applying this rule to all verbs. • This is ok for verbs such as walked, pushed or opened, but many verbs have irregular past tense forms. Name 3 verbs that don’t have regular past tense forms.
Jean Berko and the Wugs... • The majority of children naturally formed the –s plural of the fictional creature The Wug. • This also worked with other fictional creatures – heaf, cra, tor, lun – with broadly similar results.
Analysing Data For each statement decide: • Are there any ‘virtuous errors’? • What do they tell us about how the child has acquired language? Extension: What are the differences between what the child has said and what an adult would have said?
