Etymology
'avogadro' originates from Italian, specifically the surname 'Avogadro', ultimately from medieval Latin 'advocatus' (meaning 'advocate' or 'one called to aid').
'avogadro' changed from medieval Latin 'advocatus' into medieval Italian forms such as 'avogaro'/'avogadro' as a title or surname, and the modern English usage preserves the Italian surname as the eponym 'Avogadro' (used for the scientist and the constant).
Initially it referred to an 'advocate' or legal officer (from 'advocatus'); over time it became a family name and later an eponym for scientific terms (Avogadro's law, Avogadro's number).
