real [ˈriəl, ril] adj. 真的；真实的，现实的；事实上的；真诚的 adv. 真正，实在；确实地 n. 实在，现实；实数
c. 1400, "actually, in fact, in a real manner," originally in reference to the presence of Christ in the Eucharist, "substantially," from real (adj.) + -ly (2). The general sense is from early 15c. Purely emphatic use dates from c. 1600, "indeed," sometimes as a corroboration, sometimes as an expression of surprise or a term of protest; interrogative use (as in oh, really?) is recorded from 1815.
