The term 'browser-incompatible' is a compound word formed from 'browser' and 'incompatible'. 'Browser' originates from the word 'browse', which comes from the Old French 'brouster', meaning 'to feed on buds'. 'Incompatible' comes from the Latin 'incompatibilis', where 'in-' means 'not' and 'compatibilis' means 'compatible'.

'Browser' evolved from the Old French 'brouster' to the modern English 'browse', and eventually to 'browser'. 'Incompatible' has remained largely unchanged from its Latin roots.

The term 'browser-incompatible' initially referred to software or websites that could not be used with certain browsers, and this meaning has remained consistent.
