动词前缀与词义

Description

Use verb prefixes (dis-, de-, mis-, over-, re-) to change verb meaning, understanding how each prefix modifies the action expressed by the root verb

Mastery Evidence
  • Add verb prefixes to change meaning, e.g. dis- (disagree, disappear), de- (decompose, defrost), mis- (misunderstand, misbehave), over- (overlook, overreact), re- (redo, reconsider)
  • Select the appropriate verb prefix to express a specific meaning shift such as negation (dis-/mis-), reversal (de-/un-), repetition (re-), or excess (over-)
  • Distinguish verb prefixes from noun/adjective prefixes and explain how adding a prefix to a verb changes the action described
Assessment Prompt

If you give your child a verb like "appear" and ask them to use a prefix to change its meaning, can they produce words like "disappear", "reappear", or "misrepresent" and explain what the prefix does?
