Prefixes
Learn how prefixes change the meaning of words.
In Unit 2 you met suffixes (endings). Prefixes go at the beginning of a word, and they usually change its meaning.
Four from this unit, all meaning not / the opposite of:
| Prefix + root | New word | Meaning |
|---|---|---|
| dis- + regard | disregard | the opposite of regard ("with complete disregard for his safety") |
| in- + consequential | inconsequential | not important |
| im- + mortal | immortal | never dying |
| un- + daunted | undaunted | not discouraged ("with undaunted courage") |
Four different prefixes, one job! Which one a word takes is just how English settled; there's no rule.
Other prefixes have their own meanings:
| Prefix | Means | Examples |
|---|---|---|
| re- | again | rewrite, rebuild, redefine, reactivate |
| mal- | badly, wrongly | malfunction, malnutrition, malpractice |
| anti- | against | antisocial, antiseptic, anticlockwise |
| extra- | beyond, outside | extraordinary, extracurricular |
| ex- | former | ex-service, ex-captain, ex-president |
| de- | remove, undo | deactivate, defuse, decode |
All together: "Soldiers undergo extraordinary training. They learn to deactivate explosives and handle malfunctioning equipment. They stand against antisocial elements, showing unquestionable bravery. Ex-service members inspire new recruits, and their service redefines commitment."
