Synonym discussion

Sense: adjective/1

All four words describe something happening without much time passing, but they differ in degree and context. 'Instant' and 'instantaneous' both stress zero delay — 'instant' is more common in everyday language (an instant reply, instant coffee), while 'instantaneous' sounds more technical or dramatic (an instantaneous reaction in chemistry). 'Immediate' is the closest synonym to 'instant', but it also carries the idea of 'first in importance or priority' (immediate family, immediate concerns). 'Prompt' suggests action taken within a reasonable or expected time, not necessarily without any delay (a prompt response within the same day). 'Quick' is the most informal and general — it can describe anything done at speed (a quick shower, a quick look). For time-sensitive communication, 'instant' and 'immediate' are interchangeable: both 'instant feedback' and 'immediate feedback' are natural. However, for food products, only 'instant' is used — 'immediate coffee' is not a thing.

Etymology

LatinFrenchEnglish

The word 'instant' comes from Latin 'instans' (present participle of 'instare' — 'to stand upon, to be present'), via Old French 'instant'. The Latin root 'stare' (to stand) also gives us 'stand', 'state', and 'station'. The original meaning of 'being present or urgent' shifted over time toward 'happening without delay', which is its main modern sense. The food meaning ('instant coffee', 'instant noodles') appeared in the mid-20th century as a commercial term for products that could be prepared quickly.
