deflexion

noun

1. (British, countable, uncountable)Dated spelling of deflection.

   “The deflexion of particles or of radiation by scattering processes through angles greater than 90° to the original direction of motion.”

   ““Connexion” is the etymological (ie, “correct”) spelling. That is to say, our word is derived from an actual Latin noun, cf. deflexion, inflexion, and reflexion. […] And it might make life easier to abolish the letter “x”. But why should we cut off the fascinating roots of our words? I should carry on preferring “connexion”.”
