Which word is synonymous with being abnormally enlarged or swollen?

The word "turgid" specifically describes a state of being swollen or abnormally enlarged, often in relation to tissues or structures filled with fluid. In medical or scientific contexts, it refers to swelling that can be caused by various factors, such as inflammation or the accumulation of fluids. This term is frequently used to describe plants that are swollen with water or other substances, as well as certain pathological conditions in humans or animals.

The other options do not convey the same meaning. For instance, "wheedle" pertains to coaxing or persuading someone to do something, usually through flattery or deceit. "Welter" refers to a state of confusion or turmoil, often characterized by disorganized mass or jumble. "Quiescence" describes a state of inactivity or dormancy, which is not related to being enlarged or swollen in any way. Thus, "turgid" distinctly stands out as the word that aligns with the meaning of being abnormally enlarged or swollen.
