Introduction to Cryptograms
Cryptograms are letter-substitution puzzles where each letter of the alphabet is consistently replaced by another letter throughout the text. For example, every 'A' might be replaced with 'X', every 'B' with 'K', and so on. The challenge is to figure out this substitution pattern and reveal the hidden message.
Solving cryptograms can seem intimidating at first, but with a systematic approach and some practice, you'll be decoding these puzzles with ease.
Understanding the Basics
Before diving into specific techniques, it's important to understand a few key concepts:
- Substitution: In a cryptogram, each letter is consistently replaced by the same letter throughout the puzzle.
- Frequency Analysis: In English, certain letters appear more frequently than others. For example, 'E' is the most common letter, followed by 'T', 'A', 'O', and 'I'.
- Word Patterns: Certain word structures and common words can give you important clues.
Step-by-Step Approach
Step 1: Look for Single-Letter Words
In English, there are only two common single-letter words: 'a' and 'I'. If you see a single letter standing alone in your cryptogram, it's very likely to be one of these two.

If we see the single letter 'X' in this example, it's likely to be 'A' or 'I'.
Step 2: Identify Short Words
Common two and three-letter words can provide useful clues:
- Two-letter words: of, to, in, it, is, be, as, at, so, we, he, by, or, on, do, if, me, my, up
- Three-letter words: the, and, for, are, but, not, you, all, any, can, had, her, was, one, our, out, day, get, has, him
'THE' is particularly useful to identify, as it's the most common three-letter word in English.
Step 3: Look for Letter Patterns
Repeated letter patterns can reveal common words. For example:
- A word with the pattern 'XYZX' might be 'that', 'were', or 'mama'
- A longer word with a double letter in the middle like 'X--YY--Z' might be 'attention', 'different', etc.
Step 4: Use Frequency Analysis
The most common letters in English are E, T, A, O, I, N, S, H, R, D, L, U (in roughly that order). Count how often each cipher letter appears; the most frequent ones likely represent these common letters.
Common Letter Frequencies
- E: 12.7%
- T: 9.1%
- A: 8.2%
- O: 7.5%
- I: 7.0%
- N: 6.7%
- S: 6.3%
- H: 6.1%
Step 5: Context and Trial and Error
As you identify more letters, you'll start to see partially decoded words. Use context to make educated guesses about the remaining letters.
T-E Q-I-K BR--N F-X J-MPS -V-R T-E L-Z- D-G
With some letters identified, you might recognize this as "THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG"
Practical Example
Let's work through a simple example:
BX QNX DVQE BX OXQAT
- We notice 'BX' appears twice. Common repeated two-letter words include 'to', 'of', 'in', 'it', and 'we'. Since 'we' can't appear twice in this short sentence, 'to' or 'the' are likely candidates.
- Let's try 'BX' = 'to'. This gives us:
to QNX DVQE to OXQAT
- The structure now suggests a phrase like "to ___ ____ to ____". The common expression "to each their own" could fit here.
- Testing this, 'QNX' would be 'each', 'DVQE' would be 'their', and 'OXQAT' would be 'learn'.
- Checking our substitutions (B=t, X=o, Q=e, N=a, D=t, V=h, E=r, O=l, A=r, T=n), we get:
to each their learn
- This doesn't quite make sense. Let's revise: BX might be 'we'. This gives:
we QNX DVQE we OXQAT
- A common phrase could be "we are what we learn".
- Testing this new hypothesis, we get: B=w, X=e, Q=a, N=r, D=w, V=h, E=a, O=l, A=r, T=n.
- This gives us:
we are what we learn
Which makes perfect sense!
