When it comes to describing someone who is abjectly submissive, there are several synonyms that can be used to better convey the sentiment. Some terms that often come to mind include slavish, grovelling, fawning, obsequious, and servile. These words all suggest a level of deference that is extreme and often undesirable in a person, as it can be seen as weak or unassertive. Other synonyms for abjectly submissive may include cringing, cowering, subservient, and ingratiating. Regardless of the specific word chosen, the implication is always one of extreme submission and a lack of personal agency.
