# BIP39 Words Starting with I (55 words)

The 55 BIP39 words that start with I run from #898 [ice](/bip39-word/ice/) to #952 [ivory](/bip39-word/ivory/) in the English wordlist: indexes 897 to 951, or **01110000001** to **01110110111** in binary. That is 2.7% of the 2048 words, the 16th-largest of the 25 letter groups. Word length goes from 3 letters ([ice](/bip39-word/ice/) and [ill](/bip39-word/ill/)) to 8 ([identify](/bip39-word/identify/), [increase](/bip39-word/increase/) and 4 more).

13 three-letter beginnings are shared by two or more words; the largest is **"ins"**, with 5 words. The 39 words in these groups need their first four letters to be told apart, while 12 are identified by the first three, and 4 ([ignore](/bip39-word/ignore/), [iron](/bip39-word/iron/), [item](/bip39-word/item/) and 1 more) by the first two. The short word [ill](/bip39-word/ill/) also begins longer ones, so a four-letter backup keeps it whole.

Nine of the 55 words have look-alikes one letter away, such as [icon](/bip39-word/icon/) and [iron](/bip39-word/iron/). Read aloud, 18 pairs differ by a single sound, for example [inch](/bip39-word/inch/) and [inner](/bip39-word/inner/). Five spellings are shared with the [French BIP39 list](/french/), at different indexes: [image](/bip39-word/image/), [immense](/bip39-word/immense/), [impact](/bip39-word/impact/) and 2 more. Six of the words appear in the official BIP39 test vectors, among them [income](/bip39-word/income/) and [inflict](/bip39-word/inflict/).
