Sense: adjective/1
All four words describe gentle treatment, but they pick out different things. 'Merciful' assumes a clear power gap — the subject could have punished or harmed someone but chose not to; it carries a slightly formal, often religious tone (a merciful god, a merciful king). 'Lenient' is narrower and more procedural: a teacher, parent, or judge gives a lighter penalty than they could have, with no emotional or religious colour. 'Compassionate' centres the feeling of pity for someone else's suffering and does not require power over them — a stranger, a nurse, or a friend can be compassionate. 'Forgiving' focuses on the act of pardoning a specific fault and is the most everyday word of the four. So a judge who reduces a long sentence is being lenient and merciful; a nurse comforting a frightened patient is being compassionate, not merciful; a friend who lets an insult pass is being forgiving.

Etymology
From Old French 'merciable' and Latin 'merces' meaning 'reward' or 'wages', which in Church Latin came to mean 'pity' or 'compassion shown freely without payment'. English borrowed the noun 'mercy' in the 12th century and built the adjective 'merciful' soon after, originally with strong religious meaning (a merciful God who freely pardons sinners) before broadening to any kind treatment by someone with power.
