What does verminous mean?
Verminous is an adjective meaning literally full of vermin—pests such as insects, rodents, or other parasites—and figuratively loathsome, repellent, or morally corrupt. In physical descriptions, the word is especially associated with neglected buildings, food, clothing, or places where vermin have bred. Writers may also use it to condemn people, institutions, or ideas as sinister, contaminating, or degrading. Its effect is strongly derogatory rather than neutral: it presents what it describes not merely as unpleasant but as dirty, dangerous, or contemptible. Because vermin traditionally denotes collectively the objectionable creatures regarded as carriers of disease, verminous carries a sense of infestation and contamination in addition to simple visual disgust. The word is uncommon in everyday conversation but can be effective in literary, journalistic, or deliberately heightened prose. Its vividness makes it particularly useful for concentrated descriptions of physical squalor or moral corruption, though the severity of its tone should be matched carefully to the context.

Where does verminous come from?
Verminous ultimately comes from Latin verminosus, meaning “infested with worms,” formed from vermis (“worm”) and the suffix -osus. The adjective entered English in the early 17th century with its literal sense of being full of vermin. Its figurative sense of loathsome or morally tainted developed from that original meaning of infestation and contamination.
