boredom; spiritual weariness
By the time I began the second year of my B.Tech. I feared I would die of ennui, so I quit university and became a truck driver.
ennui=en (anything)+nui (new) which can be said as 'anything new?? I am filled with "boredom" with the same old stuff' ennui. when pronounced sounds quite similar to ANNOYed. now think of a person who is always annoyed with everything. such a person could be very BORING and irritating for you. Actually the previous mnemonic is better. ennui sounds like YEH NAHEEEE!!!!
