Role of agreement in linguistics planning-01917

A line of research that may be helpful in evaluating serial and parallel models concerns number agreement. In English, in order for a sentence to be grammatical there needs to be number agreement between subjects and either verbs or pronouns. Thus, we say The concerts this Summer have been wonderful, not The concerts this Summer has been wonderful, and The pitcher's fastball is his best pitch, not The pitcher's fastball is their best pitch. We sometimes make agreement errors that are instructive. For example, in sentence (5), the head noun (time) controls the correct form of the subsequent verb (is), but we sometimes err by using a form of the verb (are) that matches the immediately preceding word (games).
For example, the time for fun and games is over. (topic 90)
