Swollen, or in the act of swelling — a body part that has filled with blood or fluid and grown bigger. It is the adjective that goes with the noun 'tumescence'. Like that word, it belongs to medical writing and to deliberately formal or literary prose; nobody says it at the dinner table. In medicine it is used for swollen tissue of any kind, and there is a common surgical technique called tumescent anaesthesia, where doctors pump a lot of fluid under the skin so that the area swells and goes numb. But the word also very often refers to sexual arousal, so a writer who uses it about a person is usually either being clinical or being suggestive on purpose. Outside the body, writers use it for things that have puffed up too much — 'tumescent prose' means writing that is swollen with big words and self-importance, and that use is always an insult.

腫脹的、充血膨脹的（正式、醫學用語；也可比喻文章浮誇臃腫）
