Note
Old English þicce already meant both "thick" and "dense", and that pairing runs through the later meanings: the crowded sense and the sense for gravy and oil are close kin of this one. Thickness is taken across the smallest dimension, so a plank is thick from face to face and wide from edge to edge.

Knight's Queen of the Hustle (2007) or Kenny Attaway's Nuthouse Love (2009), it turns admiring and shades into the slang for a curvy figure. Context usually settles which is meant, since one measures bulk and the other praises curves.

They argue that this is too much to found a constitution in a pluralistic society.

Proto-Indo-European *tégus ("thick") led to Proto-Germanic *þekuz and then to Old English þicce ("thick, dense"), which became Middle English thikke. German dick, Dutch dik and Swedish tjock are related, and so is Welsh tew.
