the act of making something futile and useless (as by routine)
Adjective:
so lacking in interest as to cause mental weariness;
"a boring evening with uninteresting people" "the deadening effect of some routine tasks" "a dull play" "his competent but dull performance" "a ho-hum speaker who couldn't capture their attention" "what an irksome task the writing of long letters is" "tedious days on the train" "the tiresome chirping of a cricket" "other people's dreams are dreadfully wearisome"
