A cryptographer would write the word "EXPLETIVE" by using a specific encryption method, such as a substitution cipher or a transposition cipher. In a substitution cipher, each letter in the word would be replaced with a different letter or symbol according to a predetermined key. In a transposition cipher, the letters in the word would be rearranged according to a specific algorithm. The resulting encrypted form of "EXPLETIVE" would be a scrambled or substituted version of the original word, making it difficult for unauthorized individuals to decipher without the key.
