We use prefixes to change meaning They never change the part of speech • Many prefixes give a word a meaning which is the opposite or negative of the original

For example: we can use the prefixes dis or im: dis + agree > disagree;

im+ polite > impolite

anti + adjective/noun opposite anti- clockwise/ anti-climax

anti + noun / adjective against anti-theft device / anti-European

co + noun / verb together cohabit / cooperate / cowriter

dis + verb negative/opposite dislike / disembark / dismiss / disconnect

il + adjective opposite illegal / illiterate / illegible /

im + adjective opposite impossible / impolite / impatient / imperfect

in+adjective opposite indirect / inadequate/ informal / indecisive

inter + adjective between intercontinental / international

ir + adjective opposite irregular / irrelevant / irresponsible

mis + verb wrongly/ badly mistook / mishandle/misunderstand

over + verb too much/excess overwork / overcook/overcome/oversleep

post + noun / verb after postgraduate/ postwar

pre + noun / verb before pre- arrangement/ prejudge

pro + noun / adjective in favour of pro-Unions / pro-European

sub + adjective below subdivisionsubstandard / subway / submarine /

super + noun/ adjective greater than superhuman / superpower

trans + noun / verb / across transplant /transcontinental

un + verb / adjective negative / opposite unlock / unhappy/ unreasonable / unhappy

under + verb not enough/too little undercook / undercharge/underestimate

There are a few rules:

• We use il instead of in with words that begin with l: il + legal = illegal

• We use im instead of in with words that begin with m or p: im + polite - impolite

• We often use ir instead of in with words that begin with r: ir + responsible =

irresponsible
