For the record, and I am sure it's what you meant, a more specific description of Judy arrays is that they are a specific type of trie(though a trie is a specialization of a tree a trie is more rigorous.)

Judy Arrays are all Tries are all Trees, but only some Trees are Tries, and only some Tries are Judy Arrays.

This of i.e. as 'that is' and e.g. as "example given'.
