Homonyms and homophones are words that have the same pronunciation but different meanings and spellings. Homonyms can be spelled the same or differently, while homophones are always spelled differently. Linguistic changes over time, such as the loss of pronunciation of letters, and language contact can lead to the creation of new homophones, while other changes may eliminate existing homophones. Common English homophone examples provided are knight/night, sea/see, flower/flour, hair/hare, and won/one.

15. How do homophones exist ?
Linguists take sound change as an important factor that can
lead to the existence of homophones. In the early 18th century
the first letter of the English word KNIGHT was no longer
pronounced, making it a homophone with the word NIGHT.
Also language contact creates homophones. Some changes
over time thus create new homophones, whereas other changes
undo the homophonic status of a word.
