Sense: verb/1

For sense 1, internalize is stronger than absorb or learn. If you absorb an idea, you understand it or take it in, but it may still stay near the surface. If you internalize it, the idea starts shaping your habits and reactions. Adopt often focuses on a deliberate choice, such as adopting a policy or attitude, while internalize suggests the change has sunk deeper and now feels natural. Embrace is warmer and more enthusiastic, often showing open support. Take to heart is more emotional and is common with advice or criticism. A trainee may absorb feedback in class, but truly internalize it only when the new behaviour appears automatically at work.

Etymology

LatinEnglish

Internalize is a modern English verb built from internal, meaning 'inside', and the verb-forming ending -ize, meaning 'make or turn into'. The word first suggested bringing something inward. From that idea, English developed both the personal meaning of making beliefs part of yourself and the economic meaning of bringing hidden costs inside a price or budget.
