One Word Substitution revision for SSC CPO: identify the tested rule, check context, eliminate invalid choices and review errors.
One Word Substitution asks for a single word that expresses the meaning of a longer phrase precisely. Accuracy depends on definition, word formation and contextual fit.
SSC CPO focus: Read the complete sentence or passage, identify the tested language rule, eliminate structurally invalid choices and then verify meaning in context.
One Word Substitution revision: rule → context → elimination → answer verification → error review.
No fixed formula applies. Roots and affixes such as bio-, auto-, -logy, -phobia and -ist can provide useful meaning clues.
