Ulcerous means covered with ulcers, or having the nature of an ulcer. It is the general, describing word of the family, and it is noticeably more formal and more literary than 'ulcerated'. A doctor examining a patient today says 'ulcerated'; a writer describing a beggar's ulcerous legs, or an old medical text describing an ulcerous condition, uses 'ulcerous'.

Ulcerous 潰瘍的 means意思是 covered with ulcers佈滿潰瘍, or having the nature of an ulcer或帶有潰瘍的性質. It它 is the general, describing word是這個字族裡 of the family比較籠統、形容性的那個詞, and而且它 it is noticeably more formal and more literary明顯比較正式、比較文學 than 'ulcerated'比起 'ulcerated'. A doctor examining a patient today今天的醫生看病人時 says 'ulcerated'會說 'ulcerated'; a writer describing而作家描述 a beggar's ulcerous legs乞丐長滿潰瘍的腿, or an old medical text或舊的醫學文獻 describing an ulcerous condition描述一種潰瘍性的狀況, uses 'ulcerous'時會用 'ulcerous'.

Notice the difference in what the two words point at. 'Ulcerated' points at a particular place and says it has become an ulcer. 'Ulcerous' points at a thing or a state and says it is ulcer-like, full of ulcers, of that kind.

Notice注意 the difference兩個字指向的 in what the two words point at不同之處. 'Ulcerated' 'Ulcerated' points at指向的是 a particular place一個特定的部位, and says並且說 it has become an ulcer那裡已經變成一個潰瘍. 'Ulcerous' 'Ulcerous' points at指向的是 a thing or a state一個東西或一種狀態, and says並且說 it is ulcer-like它像潰瘍一樣, full of ulcers佈滿潰瘍, of that kind屬於那一類.

That is why 'ulcerous' also stretches easily into figurative writing — an ulcerous hatred, an ulcerous corner of the city — meaning something festering, sore, spreading and unpleasant.

That is why這就是為什麼 'ulcerous' 'ulcerous' also stretches easily也很容易延伸 into figurative writing用到比喻性的寫作裡 — an ulcerous hatred一種潰爛般的恨意, an ulcerous corner of the city城市裡一個潰爛的角落 — meaning意思是 something festering, sore, spreading and unpleasant某種在化膿、疼痛、蔓延而令人不快的東西.

In everyday modern English it is rare, and a student can go a long life without needing to produce it. But it turns up in Shakespeare, in older novels, and in writing that wants a strong, sickly image, so it is worth recognising on the page.

In everyday modern English在現代日常英語裡, it它 is rare很少見, and而且 a student一個學生 can go a long life可以一輩子 without needing to produce it都不需要自己說出這個字. But不過 it它 turns up會出現 in Shakespeare在莎士比亞裡, in older novels在舊小說裡, and in writing以及在 that wants a strong, sickly image想要營造強烈、病態意象的寫作裡, so所以 it值得 is worth recognising值得認得 on the page在書頁上.
