Here are some possibilities:
* It could be a Sanskrit word. "Shukla" in Sanskrit means "white" or "bright." It is possible the word is being used in a Malayalam context, but it's not a typical Malayalam word.
* It could be a misspelling. There might be a similar sounding Malayalam word you're thinking of. Could you please provide more context or the full phrase where you encountered this word?
Please provide more information so I can assist you better.
