how to say “to convince” in Hebrew
To succumb or to surrender, in Hebrew, is the נפעל verb להיכנע .
We will not surrender!
But since the causative הפעיל usage of this root was already taken with the Biblical להכניע – to subdue, Modern Hebrew had to come up with a new word, to convince or to subdue with words – לשכנע .
He won’t convince me easily.
לשכנע adds a ש to the original root of כ.נ.ע, creating what I like to call a superroot: ש.כ.נ.ע. Other examples of words with superroots using ש in the beginning include לשדרג – to upgrade and לשכפל – to photocopy. These words follow the פיעל verb form.
