Pronounced: ILL-kuh, adj
Notes: A handy word to know, but I’m not sure what advantage this has over the other words that could be chosen
The word inspissate means “to make or become thick or thicker”
This is a somewhat rare verb… it is derived from the Latin spissus (slow, dense), and related to the Greek word spidnos (compact) and the Lithuanian word spisti (to from a swarm).
This word appeared in English in the 1600s (Francis Bacon used it in 1626).
