What does swollen mean?
Swollen means enlarged, bulging, or puffed up, especially as a result of fluid accumulation, inflammation, injury, or another physical process. The word is commonly used in medical and everyday contexts, as in 'swollen ankles,' 'swollen glands,' or 'swollen eyes.' It can also describe something that has become excessively large or inflated, particularly in figurative expressions concerning money, pride, or institutional size. Unlike more technical alternatives such as 'edematous,' swollen is widely understood and generally neutral in tone. Its strong visual association with swelling comes from its relationship to 'swell,' whose past participle it is. In figurative use, the word often carries a slightly critical or disapproving implication when something has become larger than is considered normal or desirable.
