If you have a specific context in mind, it might help me understand what you're looking for. For example, did you see this word in a book, a song, or a conversation?
Perhaps it was meant to be one of these words:
* Echo: A sound that is repeated because of reflection.
* Cliché: A phrase or idea that has been used so often that it has become overused and unoriginal.
* Cleo: A common name, often a shortened version of Cleopatra.
Please give me more information about where you encountered the word "clecho" so I can help you understand its meaning.
