Origin: A borrowing from Latin. Etymons: Latin resonant-, resonāns, resonāre.

Etymology: < classical Latin resonant-, resonāns that sends back a sound, echoing, use as adjective of present participle of resonāre resonate v. In sense A. 2b after French résonnant (1879 (in the passage translated in quot. 1879 at sense A. 2b) or earlier in this specific use; 1538 in Middle French as †resonnant in general sense ‘resounding’). Compare Catalan ressonant (c1490), Spanish resonante (c1453), Portuguese ressonante (1589 as †resonante ), Italian risonante (a1337 as †resonante ). Compare earlier resounding adj.In specific scientific uses relating to resonance (see senses A. 1a, A. 3) after the corresponding senses of resonance n. With sense A. 1b compare slightly later resonance n. 7.

A. adj.

a. Of an object, room, etc.: causing reinforcement or prolongation of sound, esp. by synchronous vibration.

P. Andrews & A. F. Boyle Compl. Phonographic Class-bk. 28 The resonants or nasals combine, in their formation, the character of the abrupts and liquids. 1875 W. D. Whitney Life & Growth Lang. iv. 63 The result is the class of nasals (or ‘resonants’), m, n, and ng (as in singing). 1948 W. F. Twaddell in Language 24 141 /i/ before resonants was at best very rare. 1970 B. M. H. Strang Hist. Eng. ix. 406 The third sub-system consists of resonants, i.e. sounds which may or may not have syllabic function (thus corresponding to approximants, liquids and nasals in PE [= Present-day English]). 1994 J.

Nose, Throat, & Ear (ed. 4) 263 It may be nasal..growths that render the use of the nose as a resonant cavity impossible. 1945 Nature 15 Sept. 323/1 Dr. J. T. Randall applied the resonant-cavity technique to the relatively ineffective magnetron of pre-war days, and made of it a radically new and immensely powerful device. 1989 P. Horowitz & W. Hill Art of Electronics (ed. 2) xiii. 884/2 A fancier version of tunable oscillator for gigahertz frequencies uses a yttrium/iron/garnet (YIG) sphere as a magnetically tunable resonant cavity. resonant frequency n.

Bell Electric Power Transmission x. 393 When the [electrical] oscillations are strongly damped by the presence of iron, the total resonant rise is considerably diminished, but it varies less rapidly as the resonant frequency is departed from. 1934 J. P. Den Hartog Mech. Vibrations ii. 52 The forced frequency coincides exactly with the natural frequency... This important phenomenon is known as ‘resonance’, and the natural frequency is sometimes called also the ‘resonant frequency’. 2001 S. Hawking Universe in Nutshell ii. 52 (caption) Just like the strings on a violin, the strings in string theory support certain vibrational patterns, or resonant frequencies, whose wavelengths fit precisely between the two ends. resonant scattering n.

It does this through absorption and resonant scattering by intervening hydrogen gas.
