contrary

英文詞源

contrary

contrary: [14] Contrary originated as a Latin adjectival formation based on the preposition contrā ‘against’, which historically was a derivative of com or cum ‘with’. Latin contrārius passed into English via Old French contraire and Anglo-Norman contrarie. Originally contrary was pronounced with the main stress on its middle syllable, but this survives only in the sense ‘obstinately self-willed’; from the 18th century onwards, the stress has usually been placed on the first syllable.

contrary (adj.)

mid-14c., from Anglo-French contrarie, from Latin contrarius "opposite, opposed," from contra "against" (see contra).

If we take the statement All men are mortal, its contrary is Not all men are mortal, its converse is All mortal beings are men, & its opposite is No men are mortal. The contrary, however, does not exclude the opposite, but includes it as its most extreme form. Thus This is white has only one opposite, This is black, but many contraries, as This is not white, This is coloured, This is dirty, This is black; & whether the last form is called the contrary, or more emphatically the opposite, is usually indifferent. But to apply the opposite to a mere contrary (e.g. to I did not hit him in relation to I hit him, which has no opposite), or to the converse (e.g. to He hit me in relation to I hit him, to which it is neither contrary nor opposite), is a looseness that may easily result in misunderstanding; the temptation to go wrong is intelligible when it is remembered that with certain types of sentence (A exceeds B) the converse & the opposite are identical (B exceeds A).
