boycotter

To boycott — organize or take part in a collective refusal to buy from, deal with, or participate in something, as a form of protest (boycotter une marque, boycotter des élections). Widely used in political, consumer, and sports contexts.

• Plusieurs pays ont boycotté les jeux cette année-là. — Several countries boycotted the games that year.
• Les consommateurs ont décidé de boycotter la marque. — Consumers decided to boycott the brand.
• L'opposition appelle à boycotter le scrutin. — The opposition is calling for a boycott of the vote.

Boycotter always implies an organized, collective refusal as protest — don't use it loosely for simply avoiding something personally (éviter) without any protest intent behind it.

• politics The origin of 'boycott' — The French verb is a direct borrowing from English, itself coined after Charles Cunningham Boycott, a British land agent in County Mayo, Ireland, ostracized by the local community in 1880 during a rent dispute — his name became the generic term across many languages, including French.
