'recently-built' originates from the combination of 'recently' and 'built'. 'Recently' comes from the Latin word 'recens', meaning 'new' or 'fresh', and 'built' is the past participle of 'build', which comes from the Old English 'byldan', meaning 'to construct'.

'recently' changed from the Latin word 'recens' to the Old French 'recent', and eventually became the modern English word 'recently'. 'Built' evolved from the Old English 'byldan' to the modern English 'built'.

Initially, 'recently' meant 'new' or 'fresh', and 'built' meant 'to construct'. The combination 'recently-built' has retained the meaning of something constructed not long ago.
