'normogeusia' is formed from the combining prefix 'normo-' (from New Latin/Latin 'norma', meaning 'rule' or 'standard') and the combining form '-geusia' (from Greek 'γεῦσις' 'geusis', meaning 'taste').

The element '-geusia' comes from Greek 'γεῦσις' ('geusis') which entered medical Latin and formed the combining form '-geusia' used in English medical terms (e.g., 'ageusia'). The prefix 'normo-' derives from Latin 'norma' and was adopted into New Latin/medical usage as 'normo-' to indicate 'normal' or 'standard', producing the compound 'normogeusia' in modern medical English.

Individually the parts meant 'standard/rule' and 'taste'; together in modern medical usage they convey the meaning 'normal taste' or 'normal gustatory function'.
