'imprecisely-kept' originates from the combination of 'imprecisely' and 'kept', where 'imprecisely' is derived from Latin 'im-' meaning 'not' and 'precisus' meaning 'cut off, brief', and 'kept' is the past participle of 'keep'.

'imprecisely-kept' evolved from the combination of the adverb 'imprecisely' and the past participle 'kept', forming a compound adjective.

Initially, 'imprecisely' meant 'not exact', and 'kept' meant 'maintained'. Together, they describe something not maintained with precision.
