'confidently-gathered' originates from the combination of 'confidently' and 'gathered', where 'confidently' is derived from Latin 'confidere', meaning 'to trust', and 'gathered' from Old English 'gadrian', meaning 'to bring together'.

'confidently' evolved from the Latin 'confidere' through Old French 'confident', and 'gathered' from Old English 'gadrian', eventually forming the modern English term 'confidently-gathered'.

Initially, 'confidently' meant 'with trust', and 'gathered' meant 'brought together'. Over time, 'confidently-gathered' evolved to mean 'collected with assurance'.
