Negative prefixes non • The prefix non- is the most useful negative prefix, as it can be attached to virtually any noun, verb, adjective, or adverb • used to create a word that describes the complete opposite of its nonnegative form. • When affixing non- to a word, no hyphen is needed unless the stem is a proper noun. • Non- =“absence or lack of”: non-standard. • “not doing, failure to do”: non-accomplishment • If someone has a non-medical background, it simply means he has nothing to do with the medical world. • If one is talking about nonlinear motion, it is clear that he is explaining motion that is anything but in a straight line.

• Unrevealed means “not made known”: The mayor’s plans remain unrevealed as of this writing. • Non-revealed, on the other hand, is used by religious writers to mean “not founded on teachings delivered to mankind by a special emissary sent from God”: Christianity and Islam are revealed religions; Taoism is a non-revealed religion. • When faced with adding un- or non- to an adjective (including participles ending in -ed), use un- when all you mean is the adjective’s opposite. If you want to convey the lack of something, use non-.

ü non-flammable materials ü a non-renewable resource ü In non-technical every-day talk ü words and non-words ü nontransparent ü non-count nouns ü Britons are not necessarily un-American people, but they are certainly non-American.

un- attached to Latin derivatives that end in -ed / -able, (unfounded, unassailable, and unbelievable) By adding un to reliable we change the meaning of the word to not reliable. "Un" is a little stronger than "non" and, when it's attached to a participle, often means that the act implied in the participle hasn't been done yet. ü An unconnected appliance hasn't been connected ü a disconnected one has had the plug pulled. un·be·liev·er   nevernik noun a person who does not believe; a person who does not accept any, or some particular, religious belief. non·be·liev·er  ateista –noun a person who lacks belief or faith, as in god, a religion, an idea, or an undertaking. added to verbs = reversal of action: wind/unwind bind/unbind fold/unfold do/undo lock/unlock fasten/unfasten buckle/unbuckle cover/uncover wrap/unwrap done/undone added to adjectives =opposite happy/unhappy biased/unbiased dyed/undyed available/unavailable conventional/unconventiona tied/untied unknown unwanted unavailable uncool

in-, im-, il-, ir- • The in- prefix (from which im-, il-, and ir- are derived) is generally the least useful of the negative prefixes, as it only goes with certain Latinderived stems (e. g. , intolerant, inarticulate, impenetrable), • is highly conventionalized, and is identical to morphemes used in words that are not negative: ü inflammable /e: /, which means the same thing as flammable opposite of "non-flammable. " ü irradiate, which means to expose to radiation ü illuminate, which means to make luminous ü inhumane, inexplicable, insane. . . ü Use in- prefix with words that start with consonants and vowels, but not i or u. ü Im- before words that start with m or p: impossible.

Sometimes the prefixes are interchangeable. Sometimes not. Sometimes a perceived difference may exist only in the mind of the individual English speaker. Many speakers distinguish between disorganized and unorganized. ü Disorganized applies to the sort of person who stuffs receipts into the sock drawer and can never find the car keys. ü Unorganized applies to things which have not yet been arranged in an organized manner. By this reasoning, a person would be disorganized, but an office would be unorganized. • At one time, unease and disease (first syllable stressed) could be used interchangeably with the meaning “state of anxiety. ” Now disease (second syllable stressed) has taken on the meaning of “illness. ” • Angry arguments are waged over the differentiated meanings of uninterest and disinterest.
