Jollier → The word 'jollier' is derived from 'jolly' (from Middle English *jolie*, meaning cheerful or merry) and the suffix '-er' (meaning one who). Thus, 'jollier' refers to one who is more cheerful or merry than others.
Think of someone who is 'more cheerful' ('jolly') — the '-er' indicates a person, so a jollier is someone who brings more joy.
