'loosely' originates from 'loose,' which comes from Old Norse 'lauss,' meaning 'free, unattached.' 'Combine' originates from Latin 'combinare,' where 'com-' meant 'together' and 'bini' meant 'two by two.'

'loose' changed from Old English 'lēas' to Middle English 'loos,' eventually becoming the modern English word 'loose.' 'Combine' evolved from Latin 'combinare' to Old French 'combiner,' and eventually became the modern English word 'combine.'

Initially, 'loose' meant 'free or unattached,' and this meaning has largely remained the same in modern usage. 'Combine' initially meant 'to unite or join together,' which is consistent with its current meaning.
