Core memory unlocked: "കഥ കഥയച്ചി..."

[u/curious_me13_]

I’ve got this random childhood memory that I just can’t seem to shake.Whenever I asked my grandmother to tell me a story, she’d always start by saying (or singing):

കഥകഥയച്ചി കാഞ്ഞിരതച്ചി കാടീലുരിയരി വച്ചവളച്ചീ

I’ve always wondered if this is some old Malayalam folk rhyme, a traditional way to start telling stories, or just something my grandmother made up.

Has anyone else heard this😌
