Usage Note

Commonly used in retail, service, and logistics contexts. Unlike 'out of stock', which only applies to shop items, 'unavailable' can describe any resource (water, data, flights, services). It usually implies the item or service exists but is temporarily not accessible, rather than permanently gone.

Common Mistakes

That colour of car was unavailable in this brand.' (when the brand has never made that colour)
That colour is not offered in this brand.
'unavailable' suggests the item normally exists but is temporarily out of reach; use 'not offered' or 'does not come in' for permanent absence.

Sense: adjective/2

'Unavailable' is the broadest word — it covers anything from a sold-out toy to a doctor with a full schedule to a crashed website. 'Out of stock' is narrower: it only applies to products in shops or warehouses that have been bought up but will be restocked. 'Sold out' is similar but emphasises that all units were bought by customers, especially for tickets or events. 'Unobtainable' carries a stronger sense of impossibility — the thing simply cannot be had, perhaps because it no longer exists or the law forbids it. 'Inaccessible' focuses on barriers: a file can be inaccessible due to a system error, or a mountain village inaccessible because the road is closed. For everyday needs, 'unavailable' is the safest choice; choose 'sold out' for concert tickets, 'out of stock' for a popular phone, and 'inaccessible' when a physical or technical barrier is the main idea.

Etymology

LatinOld FrenchEnglish

Formed by adding the prefix 'un-' (meaning 'not') to 'available'. The word 'available' comes from the Old French verb 'avail', which combined 'a-' (towards) with 'veil' (to be worth or useful), ultimately from Latin 'valere' (to be strong or worth). The word entered English in the 15th century and was initially used in legal and commercial contexts. By the 19th century, 'unavailable' was in regular use for both people and things that could not be reached or obtained.
