## Ready when they can

- 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

## Lesson: Verb Prefixes: Small Parts, Big Meaning Changes

You already know a prefix attaches to the front of a word. Verb prefixes are special: they attach to action words like appear, do, or behave, and change the action itself, not just its size or feeling.

*(drawing: dis- + appear = disappear. The prefix flips the action to its opposite.)*

Five prefixes show up often on verbs. Dis- and mis- usually mean 'not' or 'wrong,' as in disagree and misbehave. De- means the reverse direction, as in defrost. Re- means again, as in redo. Over- means too much, as in overreact.

**Example.** Leo forgot the recipe, so he had to redo the whole cake. His sister misread the instructions and added double the sugar. Redo shows repeating the action, and misread shows the action went wrong.

One more prefix joins verbs: un-. It reverses the action, as in untie, unpack, and unzip. But watch out: some words just begin with these letters, like uncle and disaster. If you cannot split off a real action word, there is no verb prefix hiding there.

**Tip.** Before picking a verb prefix, ask: is this again (re-), wrong (mis-), not or opposite (dis-), reverse (de- or un-), or too much (over-)? The answer points you to the right prefix.

**Recap.** Verb prefixes like dis-, de-, mis-, over-, re-, and un- change what the action itself means.
