BIP39 Words Starting with K (20 words)

The 20 BIP39 words that start with K run from #973 kangaroo to #992 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, kid and kit) to 8 (kangaroo).

Five three-letter beginnings are shared by two or more words; the largest is "kit", with 4 words: kit, kitchen, kite and 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) by the first two. The short words kid and kit also begin longer ones (kid: kidney), so a four-letter backup keeps them whole.

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