cattie

n : any of various units of weight used in SE Asia (especially a

Chinese measure equal to 500 grams) [syn: {catty}]

lattice

A {partially ordered set} in which all finite subsets

have a {least upper bound} and {greatest lower bound}.

This definition has been standard at least since the 1930s and

probably since Dedekind worked on lattice theory in the 19th

century; though he may not have used that name.

See also {complete lattice}, {domain theory}.
