When we talk about something being undervalued, it means that its worth or potential is not being fully recognized. If we want to express that something is even more undervalued, we can use synonyms such as "underestimated," "underappreciated," or "overlooked." These words convey the idea that the object or concept is not getting the attention or recognition that it deserves. Other synonyms for "more undervalued" include "misjudged," "neglected," and "unnoticed." By using different words to express the same idea, we can add variety and depth to our language, and help others understand the full range of meaning behind our words.
