Much more rarely, in classic literature, abstract
can refer to someone lost in thought, as in:
- one of Doyle’s descriptions of Sherlock Holmes: "I observed that he sat frequently for half an hour on end, with knitted brows and an abstracted air,"
- Oscar Wilde’s, The Importance of Being Earnest,: "In a moment of mental abstraction, for which I never can forgive myself, I deposited the manuscript in the bassinette, and placed the baby in the hand-bag."
Much more rarely abstract
can refer to anything taken out of or separated from something else, or something stolen, as in The Adventures of Sherlock Holmes
where Doyle wrote: "...a plumber, was accused of having abstracted it from the lady’s jewel-case."
