indusium/indusio

[wehro]

According to the information I found in etymologic dictionaries, it is doubtful that indusium is derived from ind-uo. More likely is the derivation from Greek ἔν-δυσις/έν-δύω.
So it should be hyphenated in-du-si-um/in-du-si-o.

I followed Goelzer again that gives indusium, ii (induo).

For me, it seems logical to follow the same hyphenation as for induo, because it is a tunic, a garment underneath (shirt), and indusio is a verb that means to dress.

[wehro]

OK, your decision is comprehensible.

Just for completeness, I document the remark of the ThLL concerning indusium:

orig. inc. derivatur vulgo ab induere, id quod sonorum ratione vetatur

I did not find inc. in the index of abbreviations, but I think it means incerte here.
