Éric Zemmour, the far-right probable candidate for the 2022 French presidential election said (in his book La France n'a pas dit son dernier mot but also in many meetings, example) that Lenin has said:
In French: "Faites-leur manger le mot, ils avaleront la chose" or "Faites-leur avaler le mot, ils avaleront la chose."
Translated into English: "Make them swallow the word, they will swallow the thing."*
I cannot find any reference. Did Lenin or somebody else really say something similar?
