'always-allowed' is a compound word formed from 'always' and 'allowed'. 'Always' originates from Old English 'ealne weg', meaning 'all the way', and 'allowed' comes from the Old French 'alouer', meaning 'to praise or approve'.

'Always' evolved from Old English 'ealne weg' to Middle English 'alwey', and 'allowed' evolved from Old French 'alouer' to Middle English 'allowen'.

Initially, 'always' meant 'all the way' and 'allowed' meant 'to praise or approve'. Over time, 'always-allowed' came to mean 'permitted at all times'.
