One-Word Substitutions Set 3 — Actions, Behaviour and Character

This chapter covers one-word substitutions that describe how people act, what they believe, or what kind of temperament they have. Unlike Chapter 10, which listed job titles and professions, every entry here names a habit, a personality trait or an action rather than an occupation. This is one of the richest categories in SSC and banking vocabulary papers because English offers a precise single word for almost every recognisable human trait — generous, secretive, talkative, cowardly — and examiners enjoy testing whether you know the exact word rather than a rough approximation.

The chapter is organised in two parts: words describing a person's character or settled disposition, and words describing a specific action or behaviour, usually expressed as a verb. Read the definitions closely, since several entries differ only in intensity or in exactly who or what the behaviour is directed at.
