The Greek toponym's form is feminine, from the surname Flambouraris or from the profession Flambouraris, 'flag bearer', where the surname is derived. The forms Flambouraris and Flambouriaris from the word flambouro(n) 'flag', stemming from flamouron with inflection m into b and preceded by flamoulon with the liquid denominative l-l becoming l-r. The form is derived from Latin flammulum, diminutive of flamma, -ae 'flame' and the Greek ending -aris stemming from the medieval -aris, earlier arios from the Latin -arius. In Aromanian, flamburar means 'flag bearer' and derived from the Aromanian word flambura 'flag' and the suffix -ar(i).
The Aromanian name of the village stems from the personal name Floros, derived from the Aromanian word floru meaning 'blooming, shining'.
