isochronaladj.

/ʌɪˈsɒkrənəl/

Forms: Also 1700s -cronal.

Etymology: < modern Latin isochronus (Leibniz), < Greek ἰσόχρονος equal in time ( < ἰσο- , iso- comb. form + χρόνος time) + -al suffix¹. Compare French isochrone (1703 in Hatzfeld and Darmesteter).

1. = isochronous adj. 1. †isochronal line [translating Latin linea isochrona (Leibniz, 1689)] , a curve in which a heavy body descends with uniform velocity, i.e. moving through equal spaces in equal times. Obsolete.
