SWI exploration of < crypt >
This was a very rich base to explore! We found three different kinds of affixes (prefix, suffix, connecting vowel letter) and a hyphenated compound.
base word
-
< crypt >
early 15c., cripte, "grotto, cavern"
from Latin crypta "vault, cavern"
from Greek krypte "a vault, crypt"
see complete entry at etymonline
base + suffix
-
cryptic
cryptid, cryptids
base + prefix
- encrypt, encryption, encrypted, encrypting
decrypt, decryption, decrypted, decrypting
base + connecting vowel letter < o >
-
cryptocurrency
cryptozoology, cryptozoologist
hyphenated compound words

One student circled < creature > because "it seems like it must go," but we did the word sum and found that the base of < creature > is < create >.

add < cryptology > and < cryptologist > to our list
do pages 9 & 10 ("Why Johnny Had to Stay After School") and 22 & 23 ("Lincoln's Rail Fence") from Games with Codes and Ciphers
Note: If you want to make more of a lesson out of the Cardan grille, Gerolamo Cardano is in Mathematicians Are People, Too: Stories from the Lives of Great Mathematicians (vol. 2, "The Conceited Hypochondriac").
