'superficially' originates from Latin, specifically the word 'superficialis,' where 'super-' meant 'above' and 'facies' meant 'face or surface.' 'Studied' comes from the Latin 'studium,' meaning 'zeal or pursuit.'

'superficialis' transformed into the Old French word 'superficiel,' and eventually became the modern English word 'superficial.' 'Studium' evolved into the Old English 'studian,' leading to the modern 'study.'

Initially, 'superficial' meant 'pertaining to the surface,' but over time it evolved to mean 'lacking depth.' 'Study' has largely retained its original meaning of 'pursuit of knowledge.'
