Synonym discussion
Sense: adjective/3
All four words describe situations that are not steady or safe, but they differ in intensity and emphasis. 'Rocky' (B2) is the most conversational option — it suggests a relationship, project, or period that has noticeable problems but may still succeed. 'Unstable' (B1) is broader and more neutral: it describes anything likely to change or collapse, from a government to a patient's health. 'Precarious' (C1) is more formal and carries a sense of real danger — a precarious situation is one wrong step away from disaster. 'Turbulent' (C1) emphasises violent or dramatic ups and downs, often with conflict or strong emotion, as in 'a turbulent marriage full of arguments.' For everyday conversation about a difficult phase, use 'rocky'; for a truly dangerous situation, use 'precarious'; for emotional chaos, use 'turbulent.'
Common collocations
Etymology
Formed from the noun 'rock' (meaning a large stone) plus the suffix '-y', which turns nouns into adjectives meaning 'full of' or 'characterised by'. The literal sense 'full of rocks' dates back to the early 1500s. By the 1700s, 'rocky' had developed the figurative meaning 'unsteady' (like a rocking motion), and by the 1800s it was being used to describe difficult or uncertain situations.
