3. Complex derivatives
Complex derivative is a word that derives from a compound, and itself is not a “real” compound. For example, grānvināhīh ‘grievous sinfulness’ is the abstract of a bahuvrīhi grān-vināh ‘(guilty) of grievous sin’, and the suffix -īh is added to the compound and not to the last element, vināh ‘sin’.
Sometimes, a derivative is formed by adding not an affix but a “word” to another word. For example, °ravišnīh forms a number of nominal abstracts (it renders Av. °tāt-).
drustravišnīh ‘wholesomeness, health’ (Av. drvatāt- f. ‘firmness, health’). drustravišnīh ī tan. Y 9.19
pur-ravišnīh (Av. pourutāt- f. ‘large amount’) from *paru- ‘numerous, many’. purravišnīh ī mardōmān ud gōspendān. Bd 22
