Opposed to the influence of religious leaders or the church in government and public matters.
The anticlerical movement sought to reduce the power of the church in politics.
Anticlerical → It is formed from "anti-" (meaning against) and "clerical" (from Latin "clericalis", meaning relating to the clergy). The word "anticlerical" refers to opposition to the influence or power of the clergy in political or social matters.
Think of being 'against' ('anti-') the 'clergy' ('clerical') — that's why anticlerical means opposing the clergy's influence.
