This verb originally described the physical gesture of nodding one's head to signal agreement or approval, often used in Homer for Zeus nodding assent. By New Testament times it carried the broader sense of consenting or agreeing to a request. When the Ephesian Jews ask Paul to stay longer in Acts 18:20, the question is whether he nodded approval to their request. The multilingual glosses (Spanish consintió, French consentir) preserve the core idea of granting permission or agreement.
