Sense: adjective/3

All three words describe strong feelings, but they differ in tone and implication. Intense is the most neutral — it simply means the feeling is very strong, whether positive or negative (an intense interest in art / intense anger). Vehement is formal and always suggests forceful, often angry, expression of an opinion (vehement opposition to a policy). It implies energy behind the words. Passionate is positive and warm — it suggests deep emotional commitment and enthusiasm, not anger (a passionate speech about education). Fierce (sense 3) sits between intense and vehement: it carries a hint of aggression or competitive drive that intense lacks, but is less formal than vehement. A fierce loyalty is actively protective; an intense loyalty may simply be deep. Choose fierce when the emotion is strong and has an edge of fight or determination.

Etymology

Latin (ferus)Old French (fers)Middle English (fers)Modern English (fierce)

The word fierce comes from Old French 'fers' (proud, bold, fierce), which itself came from Latin 'ferus' meaning wild or untamed. In early English it described wild animals and warriors. Over time the meaning broadened to cover strong natural forces, intense emotions, and — in recent decades — bold personal style. The fashion sense (sense 5) emerged in the late 20th century, especially in LGBTQ+ ballroom culture and later in mainstream pop culture.
