English Synonyms and Antonyms
Daily is the Saxon and popular, diurnal the Latin and scientific term. In strict usage, daily is the antonym of nightly as diurnal is of nocturnal. Daily is not, however, held strictly to this use; a physician makes daily visits if he calls at some time within each period of twenty-four hours. Diurnal is more exact in all its uses; a diurnal flower opens or blooms only in daylight; a diurnal bird or animal flies or ranges only by day: in contradistinction to nocturnal flowers, birds, etc. A diurnal motion exactly fills an astronomical day or the time of one rotation of a planet on its axis, while a daily motion is much less definite.
