Synonym discussion
Sense: adjective/1
All four words describe something hard to stop, but they differ in scope and register. 'Addictive' is the strongest and most clinical, used for drugs (heroin, nicotine), foods (sugar), and screen activities (games, social media); it implies real loss of control. 'Habit-forming' is gentler and more neutral, often appearing on medicine labels and warnings, suggesting regular use rather than dependence. 'Compulsive' shifts the focus onto the behaviour and the person doing it, not the substance — we say 'compulsive shopping', not 'a compulsive snack'. 'Moreish' is informal British and limited to tasty food: 'These chips are moreish' is friendly praise; calling heroin 'moreish' would sound absurd. So: 'These cookies are addictive' (strong claim), 'moreish' (light praise), 'compulsive eating' (behaviour-focused), 'habit-forming sleeping pills' (cautious warning).

Etymology
Built in late 19th-century English from the noun 'addiction' plus the adjective ending '-ive', which marks 'having a tendency to'. 'Addiction' itself traces back through Old French to the Latin 'addictio', meaning a formal handing-over or surrender — originally a Roman legal term for awarding a debtor as a slave to a creditor. The medical sense (drug dependence) only became dominant in the early 1900s, and 'addictive' followed soon after to describe the substances doing the hooking.
