Follows or chases someone or something, often with determination; also means to continue with a goal or activity.
From Old French 'pursuir' and Latin 'prosequi' (pro- + sequi, 'to follow'). Originally meant literal chase or follow, expanded to include abstract following of goals.
The word kept its Latin root 'sequi' (follow) which also gave us 'sequence,' 'sequel,' and 'consequence'—all tracking how one thing leads to another in time or logic!
