Sense: noun/1

All four words name something that takes up a lot of mental space, but they differ in tone and intensity. 'Preoccupation' is the most neutral: a topic that keeps coming back into your thoughts, whether for good reasons or worrying ones, as in 'football was Marcus's main preoccupation.' 'Obsession' is much stronger and usually negative — it suggests the person cannot let the topic go, even when it harms them. 'Fixation' sounds clinical and points at a single, specific target the mind keeps locking onto. 'Fascination', by contrast, is positive: the topic pulls you in because it is interesting, not because it crowds out the rest of life. Compare 'a healthy fascination with insects' (curiosity), 'a preoccupation with insects' (always on the mind), and 'an obsession with insects' (cannot stop).

Etymology

LatinFrenchEnglish

Built from the Latin 'praeoccupare', meaning to seize or take hold of beforehand, formed from 'prae-' (before) plus 'occupare' (to seize, occupy). The word entered English through French in the late 1500s, first describing the act of taking something over in advance. By the 1600s the meaning had shifted from physical seizing to mental seizing — the way a single thought can take hold of the mind before any other can — which is the modern sense.
