Please, please use these words correctly

Have you ever noticed how there are some words in the English language that are constantly misused? It seems that everyone I know has been infected with the mixing up of trite, contrite, and contrive. So I am going to set the record strait, with the help of Mr. Webster and the brothers Merriam.

Contrite
Pronunciation: 'kän-"trIt, k&n-'
Function: adjective
Etymology: Middle English contrit, from Anglo-French, from Medieval Latin contritus, from Latin, past participle of conterere to grind, bruise, from com- + terere to rub -- more at THROW
: feeling or showing sorrow and remorse for a sin or shortcoming contrite criminal> contrite apology> <contrite sighs>
- con·trite·ly adverb
- con·trite·ness noun

Contrive
Pronunciation: k&n-'trIv
Function: verb
Inflected Form(s): con·trived; con·triv·ing
Etymology: Middle English controven, contreven, from Anglo-French controver, contrever, from Medieval Latin contropare to compare, from Latin com- + Vulgar Latin *tropare to compose, find -- more at TROUBADOR

2 : to bring about by stratagem or with difficulty : MANAGE contrived to win their support>

- con·triv·er noun

Trite
Pronunciation: 'trIt
Function: adjective
Inflected Form(s): trit·er; trit·est
Etymology: Latin tritus, from past participle of terere to rub, wear away -- more at THROW
: hackneyed or boring from much use : not fresh or original
- trite·ly adverb
- trite·ness noun
synonyms TRITE, HACKNEYED, STEREOTYPED, THREADBARE mean lacking the freshness that evokes attention or interest. TRITE applies to a once effective phrase or idea spoiled from long familiarity <"you win some, you lose some" is a trite expression>. HACKNEYED stresses being worn out by overuse so as to become dull and meaningless hackneyed>. STEREOTYPED implies falling invariably into the same pattern or form stereotyped and out-of-date>. THREADBARE applies to what has been used until its possibilities of interest have been totally exhausted threadbare plot>.
