Why

Oxford: British English drops the second l in enrol, fulfil and instil (but doubles it in enrolled, enrolling, fulfilled); Merriam-Webster gives enroll, fulfill and instill as American standard, with the single-l forms as variants.

Examples

  • Students can enrol (UK) / enroll (US) online from 1 August.
  • More than 400 people enrolled in the course.
