--- title: "BIP39 Words Starting with A — 136 Mnemonic Seed Phrase Words" url: "https://bip39-phrase.com/bip39-words/a/" language: "en" updated: "2026-10-19T00:00:00+00:00" --- # BIP39 Words Starting with A (136 words) The 136 BIP39 words that start with A run from #1 [abandon](/bip39-word/abandon/) to #136 [axis](/bip39-word/axis/) in the English wordlist: indexes 0 to 135, or **00000000000** to **00010000111** in binary. That is 6.6% of the 2048 words, the 3rd-largest of the 25 letter groups. Word length goes from 3 letters ([act](/bip39-word/act/), [add](/bip39-word/add/) and 8 more) to 8 ([abstract](/bip39-word/abstract/), [accident](/bip39-word/accident/) and 4 more). 27 three-letter beginnings are shared by two or more words; the largest is **"act"**, with 5 words. The 77 words in these groups need their first four letters to be told apart, while 56 are identified by the first three, and 3 ([aerobic](/bip39-word/aerobic/), [ahead](/bip39-word/ahead/) and [axis](/bip39-word/axis/)) by the first two. 29 of the 136 words have look-alikes one letter away, such as [act](/bip39-word/act/) and [art](/bip39-word/art/). Swapping two neighbouring letters turns [act](/bip39-word/act/) into [cat](/bip39-word/cat/). Read aloud, 80 pairs differ by a single sound, for example [access](/bip39-word/access/) and [axis](/bip39-word/axis/). Five spellings are shared with the [French BIP39 list](/french/), at different indexes: [abandon](/bip39-word/abandon/), [amateur](/bip39-word/amateur/), [angle](/bip39-word/angle/) and 2 more. 22 of the words appear in the official BIP39 test vectors, among them [abandon](/bip39-word/abandon/) and [ability](/bip39-word/ability/). ## All 136 BIP39 words starting with A | # | Word | Binary | IPA |
