The phrase "more monkish" refers to someone who leads a lifestyle similar to that of a monk, usually characterized by simplicity, solitude, and religious devotion. The opposite of this can be a phrase like "less monkish," which implies someone who is more outgoing and social, less religiously devoted, and more interested in worldly pleasures. Some possible antonyms include "social," "worldly," "outgoing," "hedonistic," "indulgent," "materialistic," and "luxurious." These words describe people who value social interaction, entertainment, pleasure, and material possessions more than they do solitude, simplicity, and religious devotion, which are the hallmarks of a monkish lifestyle.
