These nouns denote patterns of behavior established by continual repetition. Habit applies to a behavior or practice so ingrained that it is often done without conscious thought: "Habit rules the unreflecting herd" (William Wordsworth).
Practice denotes an often chosen pattern of individual or group behavior: "You will find it a very good practice always to verify your references, sir" (Martin Joseph Routh).
Custom is behavior as established by long practice and especially by accepted conventions: "No written law has ever been more binding than unwritten custom supported by popular opinion" (Carrie Chapman Catt).
Wont refers to a customary and distinctive practice: "Miss Roxy sat bolt upright, as was her wont" (Harriet Beecher Stowe).
