TRAVAIL . The Fr. travail , meaning ‘labour or trouble,’ was taken into Eng. without alteration of meaning or spelling. This spelling is found in AV [Note: Authorized Version.] , and it is still sometimes used, especially for the labour of child-birth. But the spelling ‘travel’ afterwards became common, and the word was then confined to journeying, that being a recognized form of toii and trouble in those days. In Numbers 20:14 ‘Thou knowest all the travel that hath befallen us,’ the meaning is more than journeying , and so RV [Note: Revised Version.] spells the word ‘travail,’ which was the original spelling of AV [Note: Authorized Version.] also.
