'narrowly-focused' originates from the combination of 'narrowly' and 'focused', where 'narrowly' is derived from 'narrow', meaning 'limited in extent', and 'focused' from 'focus', meaning 'center of interest or activity'.

'narrowly' evolved from the Old English word 'nearu', meaning 'constricted', and 'focused' from the Latin word 'focus', meaning 'hearth' or 'fireplace'.

Initially, 'narrowly' meant 'constricted or tight', and 'focused' meant 'center of interest', evolving to mean 'having a specific or limited scope'.
