Prefixes as an aid to spelling
A prefix is a group of letters placed at the start of aroot word to change its meaning. Some complicated words
are less difficult to spell if you are familiar with
prefixes.
Here are some common examples in the following list:
| PREFIX | MEANING | EXAMPLES |
| anti- | against or opposite to | anticlockwise, antibiotic |
| auto- | self | autobiography, automat |
| dis- | not, or away | dissimilar, disconnect |
| in- | not | insane, inhuman |
| il- | not | illogical, illegal |
| im- | not | immature, improbable |
| ir- | not | irrelevant, irregular |
| inter- | between | international, intermarry |
| mis- | wrong | misunderstand, misspell |
| post- | after | postnatal, postscript |
| pre- | before | prenatal, prehistoric |
| pro- | for, or forward | propose, pro-British |
| re- | again, or back | rewrite, reconsider |
| sub- | under | submarine, substandard |
| super- | above | supervisor, superhuman |
| trans- | across | transport, transplant |
| un- | not, or in reverse | unfinished, unarmed |
