'meticulously-maintained' originates from the Latin word 'meticulosus,' meaning 'fearful' or 'timid,' combined with the English word 'maintain,' from the Old French 'maintenir,' meaning 'to hold in hand.'

'meticulosus' transformed into the English word 'meticulous,' and 'maintenir' became 'maintain' in English, eventually forming the compound adjective 'meticulously-maintained.'

Initially, 'meticulous' meant 'fearful,' but over time it evolved to mean 'showing great attention to detail,' while 'maintain' has largely retained its meaning of 'to keep in a certain state.'
