dvanda compound = two or more members instead of being connected with the participle 'ca' getting joined together and function as copulative compound. Examples nāmarūpaṃ (mentality-materiality); samaṇabrāhmaṇā (ascetics & brahmins)
tappurisa compound = cases where the first member depends on the second (dependent compounds). Example sīlasampanno (perfection of morality); bhikkusaṅgho (community of monks); dukkhasamudayo (arising of suffering); kālaṃkato (end of time)
MN 18 is a very good example but this might be against the view of a dvanda compound and might support my considering of a tappurisa compound. Below translations of the compound papañcasaññāsaṅkhā:User1249x wrote: ↑Sun Jul 22, 2018 2:37 am the statement suggested for translation also makes sense and would seem very reasonable and supported by Sutta thus;What one perceives, one thinks about. What one thinks about, one objectifies. Based on what a person objectifies, the perceptions & categories of objectification assail him/her with regard to past, present, & future forms cognizable via the eye.

yaṃ papañceti tatonidānaṃ purisaṃ papañcasaññāsaṅkhā samudācaranti
What you proliferate about is the source from which a person is beset by concepts of identity that emerge from the proliferation of perceptions. (Sujato)
Based on what a person objectifies, the perceptions & categories of objectification assail him/her (Thanissaro)
what obsesses one is the origin of the number of perceptions and obsessions which assail a man (Horner)
With pananca as source, perceptions and notions [born of] mental proliferation beset a man - Bodhi
Bhikkhu Bodhi's footnote says he questionably decided to treat "saññāsaṅkhā" as a dvanda compound thus perceptions and notions.
But Bhikkhu Sujato, has appeared to treat papañcasaññā as a tappurisa compound (although in the reverse order as usually treated) thus proliferation of perceptions; even though in SN 40.1 Sujato treated saññāmanasikārā as a dvanda compound.
I prefer Horner's literal translation.
