FCC: Lazy Or Just Lackadaisical?
Lazy implies the deliberate avoidance of work in order to spare oneself effort. Lackadaisical implies lack of purpose. The lazy person has a purpose. The lackadaisical person is content to let things happen.
The adjective lackadaisical derives ultimately from the word lack in the Middle English sense of “loss, failure, reproach, shame.” When people were overcome by the sadness, unfairness, or futility of life, they would put the back of their hands to their foreheads and exclaim “Ah, lack!”
“Ah, lack” became the word alack. Then came the expression “Alack the day!”
On a day, alack the day!
Love, whose month was ever May,
Spied a blossom passing fair,
Playing in the wanton air… Shakespeare, “Love’s Perjuries”
“Alack the day” contracted to the interjection lackaday:
Ah, lack-a-day! it’s a troublesome world!
Lack-a-day became lack-a-daisy:
The carpenter..said ‘lack-a-daisy!’ when he saw that the old theatre was pulled down.
The whimsical adjective lackadaisical derives from the exclamation lackadaisy.
The OED gives this definition of lackadaisical:
Resembling one who is given to crying ‘Lackaday!’; full of vapid feeling or sentiment; affectedly languishing. Said of persons, their behaviour, manners, and utterances.
Merriam-Webster defines lackadaisical this way:
lacking life, spirit, or zest : devoid of energy or purpose
