Malayalam Kochupusthakam Kambi Kadakal Pdf Updated Info

First, I should clarify the term. "Kochupusthakam" probably refers to a small grammar book used for beginners. "Kambi" in Malayalam could mean a stick or a type of question. "Kadakal" might be a place or a term specific to grammar. I need to verify that. Maybe "kambi kadakal" is a part of the book's title, highlighting exercises or examples using sentences (kambi could be sentences or structures).
