Synonym discussion

Sense: noun/1

All four words describe how easy it is to get to or get hold of something, but they differ in focus. 'Accessibility' is the broadest: it covers physical reach, ease of obtaining, and even ease of using or understanding. 'Availability' shifts the focus to whether the thing is on hand right now — a doctor may be highly accessible (close, easy to reach) but not available until next week. 'Reachability' is more technical and is mostly used in transport networks and telecommunications, e.g. 'reachability of remote villages by ferry'. 'Proximity' is the narrowest, covering only physical closeness — 'proximity to the station' says nothing about price, hours, or step-free entry. So you might say: 'The clinic's proximity is great, but its availability is poor and its accessibility for wheelchair users still needs work.'

Etymology

LatinLate LatinMiddle FrenchEnglish

The noun was formed in English in the early 1600s by adding the abstract-noun ending '-ity' to the adjective 'accessible'. 'Accessible' itself came into late Middle English from Late Latin 'accessibilis', built on the Latin verb 'accedere' meaning 'to come near' or 'to approach' (from 'ad-' 'to' + 'cedere' 'to go'). For most of its history the word meant simply 'the quality of being able to be reached'. The disability-related senses (buildings, then digital products) grew out of civil-rights and design-standards work from the 1960s onwards, and the 'easy to understand' sense, applied to art and writing, became common in twentieth-century criticism.
