Is there a specific name for adjectives such as porcine that are special forms of words meaning "relating to" some other thing? They are often:
- based on classical words and end in 'al' and 'ine'
- can exist separately and mean differently than tyical English endings used to create adjectives (such as 'y' or 'ly', or 'ish')
- more literal and restrictive than English endings when both exist
floral means "relating to flowers", even though flowery is a valid and more English word. But floral means more strictly and literally "relating to flowers" while flowery is often used in a figurative sense, such as "flowery language".
porcine means literally "relating to pigs", while piggish and porky are more English words but almost never meant literally.
piscine means literally "relating to fish", while fishy is the obvious English word that has both literal ("salmon is less fishy than cod") and figurative ("a fishy situation") meanings.
Their origin in English probably comes from scientific use, where literal and specific meanings are important, and classical sources are almost always used to create new terms. Still, is there a name for this? For bonus points, are there any examples that are not clasically derived words?
