# BIP39 Words Starting with Y (6 words)

The 6 BIP39 words that start with Y run from #2039 [yard](/bip39-word/yard/) to #2044 [youth](/bip39-word/youth/) in the English wordlist: indexes 2038 to 2043, or **11111110110** to **11111111011** in binary, so all of them begin with the bits 1111111\. That is 0.3% of the 2048 words, the 24th-largest of the 25 letter groups. In list order they are [yard](/bip39-word/yard/), [year](/bip39-word/year/), [yellow](/bip39-word/yellow/), [you](/bip39-word/you/), [young](/bip39-word/young/) and [youth](/bip39-word/youth/), from 3 to 6 letters long.

One three-letter beginning is shared by two or more words: **"you"** begins [you](/bip39-word/you/), [young](/bip39-word/young/) and [youth](/bip39-word/youth/). The 3 words in these groups need their first four letters to be told apart, while 2 are identified by the first three, and one ([yard](/bip39-word/yard/)) by the first two. The short word [you](/bip39-word/you/) also begins longer ones ([you](/bip39-word/you/): [young](/bip39-word/young/) and [youth](/bip39-word/youth/)), so a four-letter backup keeps it whole.

Three of the 6 words have look-alikes one letter away: [yard](/bip39-word/yard/) ([card](/bip39-word/card/) and [hard](/bip39-word/hard/)), [year](/bip39-word/year/) ([near](/bip39-word/near/), [pear](/bip39-word/pear/) and [wear](/bip39-word/wear/)) and [youth](/bip39-word/youth/) ([south](/bip39-word/south/)). Read aloud, 14 pairs differ by a single sound, for example [year](/bip39-word/year/) /jɪə/ and [you](/bip39-word/you/) /juː/ or [deer](/bip39-word/deer/) /dɪə/. Two of the words appear in the official BIP39 test vectors: [year](/bip39-word/year/) (vectors #2, #6 and #10) and [yellow](/bip39-word/yellow/) (vector #2).
