'odd-shaped' originates from the combination of 'odd' and 'shaped', where 'odd' meant 'strange or unusual' and 'shaped' refers to the form or outline of an object.

'odd' changed from the Old Norse word 'oddi', meaning 'point or triangle', and 'shaped' from the Old English 'sceapian', meaning 'to create or form'.

Initially, 'odd' meant 'point or triangle', but over time it evolved into its current meaning of 'strange or unusual'.
