'haphazardly-sent' originates from the combination of 'haphazardly' and 'sent', where 'haphazardly' means 'in a random manner' and 'sent' refers to the act of dispatching something.

'haphazardly' evolved from the Middle English word 'hap hasard', meaning 'chance' or 'risk', and 'sent' has remained consistent in its meaning of dispatching or transmitting.

Initially, 'haphazardly' meant 'by chance', but over time it evolved to imply a lack of order or planning, which is reflected in the modern usage of 'haphazardly-sent'.
