A definition on Merriam Webster says:
especially : marked by indulgence in things (such as drink or promiscuous sex)
deemed vices (source)
This definition is a bit confusing, because I am not sure if it means:
marked by indulgence in things and deemed vices
Is that line saying that "deemed vices" is among the things one indulges in? If this is the case, is "deemed vices" a noun phrase here and "deemed" an attributive modifier?
Having checked several dictionary pages on "deem", I haven't found an example of "deemed" + noun. Is "deemed" used as an attributive modifier before a noun? If so what does it mean? "reputed"?
