'suitably-left' is a compound word formed from 'suitably' and 'left'. 'Suitably' originates from the word 'suit', which comes from Old French 'suite', meaning 'attendance' or 'pursuit'. 'Left' comes from Old English 'lyft', meaning 'weak' or 'foolish', but evolved to mean the opposite of 'right'.

'Suitably' evolved from the Old French 'suite' to the modern English 'suit', and 'left' evolved from Old English 'lyft' to its current meaning.

Initially, 'left' meant 'weak' or 'foolish', but over time it evolved into its current meaning of 'opposite of right'.
