There are several ways to say "taking for granted." Some synonyms include underestimating, overlooking, neglecting, underrating, and devaluing. Each of these terms refers to the behavior of not appreciating someone or something or failing to recognize their value. When individuals underestimate or underrate someone or something, they do so knowingly or unknowingly. Neglecting and overlooking, on the other hand, are behaviors that result from carelessness or indifference. When individuals devalue someone or something, they express low regard and underestimate the worth of what is being observed. Regardless of the term used, taking anything for granted can be damaging, and expressions of gratitude and appreciation can go a long way in building strong relationships.
