Prefixes as an aid to spelling

    A prefix is a group of letters placed at the start of a
    root 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
