Comparative form of fleshly; more carnal, more bodily, more concerned with physical desires, or more spiritually debased.
From 'fleshly' (flesh + -ly adjectival suffix) plus '-er' (comparative). 'Fleshly' itself is an older, somewhat archaic adjective emphasizing the bodily and carnal aspects of 'fleshy.'
Religious texts used 'fleshly' to describe temptation and sin—the 'fleshly desires' they warned against were coded language for sensuality and earthly pleasures that distracted from spiritual life!
