What is the term for the compound verbs formed by prefixing prepositions to the verb root, a feature already productive in Homeric Greek and still used today?

• A parasyntheta
• B prepositional compounds ✓
• C augmented roots
• D tmesis

Greek has a highly productive system of compounding verbs with prepositional prefixes (kata-, ana-, para-, apo-, etc.) that modify the verb's meaning; this Indo-European inheritance is already fully developed in Homer.
