# BIP39 Words Starting with K (20 words)

The 20 BIP39 words that start with K run from #973 [kangaroo](/bip39-word/kangaroo/) to #992 [know](/bip39-word/know/) in the English wordlist: indexes 972 to 991, or **01111001100** to **01111011111** in binary, so all of them begin with the bits 011110\. That is 1.0% of the 2048 words, the 22nd-largest of the 25 letter groups. Word length goes from 3 letters ([key](/bip39-word/key/), [kid](/bip39-word/kid/) and [kit](/bip39-word/kit/)) to 8 ([kangaroo](/bip39-word/kangaroo/)).

Five three-letter beginnings are shared by two or more words; the largest is **"kit"**, with 4 words: [kit](/bip39-word/kit/), [kitchen](/bip39-word/kitchen/), [kite](/bip39-word/kite/) and [kitten](/bip39-word/kitten/). The 12 words in these groups need their first four letters to be told apart, while 7 are identified by the first three, and one ([kangaroo](/bip39-word/kangaroo/)) by the first two. The short words [kid](/bip39-word/kid/) and [kit](/bip39-word/kit/) also begin longer ones ([kid](/bip39-word/kid/): [kidney](/bip39-word/kidney/)), so a four-letter backup keeps them whole.

Nine of the 20 words have look-alikes one letter away, such as [keen](/bip39-word/keen/) and [keep](/bip39-word/keep/) or [kid](/bip39-word/kid/) and [kind](/bip39-word/kind/); all pairs are listed below. Read aloud, 62 pairs differ by a single sound, for example [keen](/bip39-word/keen/) /kiːn/ and [key](/bip39-word/key/) /kiː/ or [bean](/bip39-word/bean/) /biːn/. Two of the words appear in the official BIP39 test vectors: [kick](/bip39-word/kick/) and [knee](/bip39-word/knee/).
