Is there an analogous formation in the Latin adjectives spissus "thick", crassus "thick", grossus "thick, fat, large, bulky", bassus "short"? Cou we add de:nsus "dense" to this group? Are they vernacular Latin words or loanwords from Italic, Celtic, Ligurian neighboors?
crassus < *kratsos ? akin to Greek kratos (g. krateos) < *krh2tos- > *krh2ts-o- ?
