   • 2005 April 11, Philip Howard, “Modern Manners”, in The Times‎^[1], London: News UK, →ISSN, →OCLC, archived from the original on 17 April 2026:

     “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”.
