'pavement-only' is a compound word formed from 'pavement' and 'only'. 'Pavement' originates from Middle English, derived from Old French 'pavement', from Latin 'pavimentum', meaning 'a floor beaten or rammed down'. 'Only' comes from Old English 'ānlic', meaning 'unique' or 'singular'.

'Pavement' evolved from the Latin 'pavimentum' through Old French 'pavement', while 'only' transformed from Old English 'ānlic' to the modern English 'only'.

The term 'pavement' initially referred to a 'beaten or rammed floor', but now commonly refers to 'a paved surface'. 'Only' has retained its meaning of 'solely' or 'exclusively'.
