Just because two words are close in sound does not mean that they are etymologically
similar. You are confusing similarity in phonology
, the sound of words, with similarity in etymology
, the history of a word. There are many words in different languages which are superficially similar in sound completely by accident, and the words have different histories.
The French word for cinnamon is cannelle
. That word is probably etymologically related to the Spanish word canela
. But cannelle and Chanel
don't have to be related any more than English word pairs like cake/shake, cot/shot, or cunning/shunning have to be go back to the same ancient words.
