What characterizes the u-shaped grammar curve in language development?

• A. Kids get worse after a little and then better again
• B. Kids improve steadily with no dips
• C. Kids revert to primitive speech
• D. Kids show no recognizable pattern

Answer: (A)

The u-shaped grammar curve captures how children move from using fixed language chunks to applying general grammar rules, and then back to mature usage. Early on, kids often rely on memorized phrases or irregular forms as whole units. As they begin to generalize grammar rules, they apply them broadly, leading to temporary mistakes like adding “-ed” to all verbs or using the wrong past tense (for example, saying “goed”). This causes a decline in grammatical accuracy. With more experience and learning, they re-stabilize, remembering the correct forms and exceptions, and their grammar becomes accurate again. So the characteristic pattern is a brief dip after initial success, followed by improvement.
