Put a mark on the wall! I noticed something interesting about this week's theme. It occurred to me that the current definition of assorted is self-contradictory.
To sort means to separate a group into smaller groups
according to some characteristic - size, color, weight, value,etc.
Look at Webster 1913:

Webster's 1913 Dictionary

Definition: \As*sort"ed\ ([a^]s*s[^o]rt"[e^]d), a.
Selected; culled.
