'clumsily-shown' is a compound word formed from 'clumsily' and 'shown'. 'Clumsily' originates from the word 'clumsy', which comes from the Scandinavian word 'klumsa', meaning 'to stumble'. 'Shown' is the past participle of 'show', which comes from the Old English 'scēawian', meaning 'to look at'.

'Clumsily' evolved from the Middle English 'clomsen', and 'shown' evolved from the Old English 'sceawian', eventually forming the modern English compound 'clumsily-shown'.

Initially, 'clumsy' meant 'awkward in movement', and 'shown' meant 'to display'. Together, they evolved to describe something presented in an awkward manner.
