The term 'collaboratively-kept' is a compound word formed from 'collaboratively' and 'kept'. 'Collaboratively' originates from the Latin 'collaborare', meaning 'to work together', and 'kept' is the past participle of 'keep', from Old English 'cēpan', meaning 'to seize, hold'.

'Collaboratively' evolved from the Latin 'collaborare', through Middle English, while 'kept' is derived from Old English 'cēpan'. The combination into 'collaboratively-kept' is a modern English construct.

Initially, 'collaboratively' meant 'working together', and 'kept' meant 'held or preserved'. Together, they convey the idea of something maintained through joint effort.
