hortatory (adj.)

"urging to some course of conduct or action," 1580s, from French hortatoire and directly from Late Latin hortatorius "encouraging, cheering," from hortatus, past participle of hortari "exhort, encourage, urge, incite, instigate," intensive of horiri "urge, incite, encourage," from PIE root *gher- (2) "to like, want." Older in English is hortation (1530s), from Latin hortationem.
