'Unteach' is more specific and active. It implies a deliberate pedagogical or corrective action aimed at a previously learned skill or belief. 'Make someone forget' is broader and can be accidental or passive.
Yes, but it's nuanced. It is positive in intent (e.g., unteaching racism) but describes a process that is inherently challenging because it involves removing something negative. The outcome is positive, the process is difficult.
Not exactly. 'Teachable' often means willing and able to learn. 'Unteachable' primarily means incapable of being taught, often due to stubbornness or a fixed mindset. It is a stronger, more negative term than simply 'not teachable'.
