unassertive

This term describes a personality trait characterized by a tendency to defer to others and a reluctance to engage in conflict. It carries a slightly negative connotation of passivity or weakness, suggesting a failure to advocate for oneself even when justified. It is frequently used in professional evaluations or psychological profiles to describe someone who avoids taking charge.

In contrast to being aggressive or assertive, an unassertive person may experience internal frustration because their needs remain unmet. The word implies a lack of outward force rather than a lack of internal desire or opinion.
