When it comes to describing something as "more defined," there are plenty of synonyms to choose from. For example, the term "sharper" could be used, indicating that the lines or edges of the object in question are more distinct. "Clearer" could also be used, suggesting that the details of the object are more visible and easy to discern. "Enhanced" is another potential synonym, emphasizing the idea that the object has been improved in some way to make it more defined. Other options might include "accentuated," "crisper," "well-defined," or "pronounced." Ultimately, the right synonym will depend on the context of the sentence and the tone you want to convey.
