What's the difference between i.e. and e.g.?
early 13c., "philosophical or theological problem;" early 14c. as "utterance meant to elicit an answer or discussion," also as "a difficulty, a doubt," from Anglo-French questiun, Old French question "question, difficulty, problem; legal inquest, interrogation, torture," from Latin quaestionem (nominative quaestio) "a seeking, a questioning, inquiry, examining, judicial investigation," noun of action from past participle stem of quaerere "ask, seek" (see query (v.)).
No question "undoubtedly" is from mid-15c; no questions asked "accountability not required" is from 1879 (especially in newspaper advertisements seeking the return of something lost or stolen). Question mark is from 1849, sometimes also question stop (1862); figurative use is from 1869. To be out of the question (c.1700) is to be not pertinent to the subject, hence "not to be considered."
late 15c., from question (n.) and from Middle French questionner "ask questions, interrogate, torture" (13c.), from question (n.). Related: Questioned; questioning. Alternative questionize attested from 1847.
in law, the interrogation of a witness by attorneys or by a judge. In Anglo-American proceedings an examination usually begins with direct examination (called examination in chief in England) by the party who called the witness. After direct examination the attorney for the other party may conduct a cross-examination of the same witness, usually designed to cause him to explain, modify, or possibly contradict the testimony he provided on direct examination. It may be followed by redirect examination and even, in some U.S. jurisdictions, by re-cross-examination.
