Mnemonic Major System

The Mnemonic Major System helps you to remember a string of digits (a phone number, a PIN, the first digits of Pi, etc.) by turning numbers into words. Words are much easier to remember than digits.

The trick: certain consonant letters map to digits 0–9. Some letters and spaces are completely neutral — they evaluate to nothing, but they are the glue that lets you build real, meaningful words and sentences around the significant consonants. Because the mapping is fixed and unambiguous, a word or sentence always translates to exactly the same number. The mapping is one to many, meaning there's many words translating to the same number.

The goal is to find a word or a sequence of words that:

  1. encodes precisely the digits you want to remember, and
  2. means something memorable — ideally something you can visualize or that connects to the number itself (eg. connects to a person whose phone number you'd like to remember).

The mapping

The mapping is a bit different for Polish and English language. Note that a phonetic pronounciation counts, not the actual letters, particularly in English.

Polish

Digit Sounds Mnemonic
0 Z S Ź Ś "Z" for zero
1 T D "T" has one vertical stroke, like 1
2 N Ń "N" has 2 vertical strokes
3 M "M" has 3 vertical strokes
4 R "czteRy" has R
5 L "L" - Roman numeral for 50
6 SZ CZ Ż DZ "SZeść" and other rustlings
7 K G 7 and K have diagonal stroke
8 F W Fedora logo: f in 8
9 P B P is flipped 9

Note that hard letters and their soft counterparts are always in the same sections.

Neutral (ignored): vowels A Ą E Ę I O Ó U Y and C H CH J Ć Ł.

English

Digit Sounds
0 S /s/, Z /z/
1 T /t/, D /d/
2 N /n/
3 M /m/
4 R /r/
5 L /l/
6 SH /ʃ/, CH /tʃ/, J /dʒ/
7 K /k/, G /g/
8 F /f/, V /v/, TH /θ/
9 P /p/, B /b/

Vowels, W, H, and silent letters are neutral (ignored).

Examples

Take the phrase "mój tort ulubiony" that encodes digits of pi (assosiate with "pie" or round pie chart). Read only its significant consonants:

m ó j   t o r t   u l u b i o n y
3       1   4 1     5   9     2

That is 3 141 592 — the first 7 digits of π. The letters ó, j, o, u, i, o, y and the spaces are all neutral fillers — they contribute nothing to the number, but they turn a bare consonant sequence into a real, vivid phrase that sticks in your memory.

Another one: "negatywna wada":

negatywna wada
2 7 1 82  8 1
resolves to 2 718 281 - first digits of e number.

Short words work great for small numbers:

Word Breakdown Number
żaba ż=6, b=9 69
muchomor m=3, (ch=neutral), m=3, r=4 334
tapir t=1, p=9, r=4 194
rain r=4, n=2 42
film f=8, l=5, m=3 853

MemGen — find the word for you

Searching for a matching word by hand can be a tedious process. MemGen is a free browser tool that facilitates it — type a number, get a list of matching Polish and English words. Choose the ones that resonate with the encoded meaning.

You can add spaces to work on segments separately: 3 141 592 gives results for each chunk independently.
