BIP39 Words Starting with S (250 words)

The 250 BIP39 words that start with S run from #1518 sad to #1767 system in the English wordlist: indexes 1517 to 1766, or 10111101101 to 11011100110 in binary. That is 12.2% of the 2048 words, the largest letter group. Word length goes from 3 letters (sad, say and 6 more) to 8 (scissors, scorpion and 9 more).

61 three-letter beginnings are shared by two or more words; the largest is "sta", with 10 words. The 205 words in these groups need their first four letters to be told apart, while 45 are identified by the first three. The short words sad, sea, ski and sun also begin longer ones, so a four-letter backup keeps them whole.

119 of the 250 words have look-alikes one letter away, such as sad and sand. Swapping two neighbouring letters turns sign into sing. Two words sound identical: sauce and source (/sɔːs/). Read aloud, 243 pairs differ by a single sound, for example sad and seed. Twelve spellings are shared with the French BIP39 list, at different indexes: salon, science, sentence and 9 more. 34 of the words appear in the official BIP39 test vectors, among them salt and sausage.

Similar-looking words to check

These 154 pairs differ by one letter or by two swapped neighbouring letters, with at least one word starting with S. Both words are valid, so a slip between them passes the word check and only the checksum can catch it.
