'normally-adjusted' originates from the combination of 'normal' and 'adjusted', where 'normal' comes from Latin 'normalis', meaning 'conforming to a standard', and 'adjusted' comes from Old French 'ajuster', meaning 'to bring into line'.

'normally-adjusted' evolved from the combination of 'normal' and 'adjusted', which were used separately in Middle English and eventually combined in modern English.

Initially, 'normal' meant 'conforming to a standard', and 'adjusted' meant 'brought into line'. Together, they evolved to mean 'adjusted in a typical manner'.
