'weather-independent' is a compound word formed from 'weather' and 'independent'. 'Weather' originates from Old English 'weder', meaning 'air, sky, breeze', and 'independent' comes from the prefix 'in-' meaning 'not' and 'dependent', which originates from Latin 'dependere', meaning 'to hang down'.

'Weather' evolved from Old English 'weder' to Middle English 'weder', and 'independent' evolved from Latin 'independens' to Middle English 'independente'.

Initially, 'weather' referred to atmospheric conditions, and 'independent' meant 'not relying on others'. Combined, they describe something unaffected by weather.
