Noah Webster's Dictionary (a.) Rarely visited; seldom or never resorted to by human beings; as, an unfrequented place or forest.

Multi-Version Concordance Unfrequented (1 Occurrence) Mark 1:45 But the man, when he went out, began to tell every one and to publish the matter abroad, so that it was no longer possible for Jesus to go openly into any town; but He had to remain outside in unfrequented places, where people came to Him from all parts.
