The word "admonish" appears multiple times in the Bible and generally means to warn or reprimand someone for their behavior in order to correct them and help them avoid wrongdoing or harm.
For example, in the New Testament book of Colossians 3:16, it says, "Let the message of Christ dwell among you richly as you teach and admonish one another with all wisdom through psalms, hymns, and songs from the Spirit, singing to God with gratitude in your hearts."
Similarly, in the book of Ephesians 6:4, it says, "Fathers, do not exasperate your children; instead, bring them up in the training and instruction of the Lord."
In both cases, the idea of admonishing is connected to teaching and guiding others in a loving and constructive way, rather than simply criticizing or condemning their actions.
