How do you write an informal letter in Malayalam?

To write an informal letter in Malayalam, you would typically start with a salutation such as "ആദരാഞ്ജലികൾ" (Aadaraanjali) or "സ്നേഹം" (Sneham). Then, you can introduce yourself and the purpose of your letter in a conversational tone. Use simple and colloquial language to communicate your message effectively. Finally, conclude your letter with a closing such as "നന്ദി" (Nandi) or "സ്നേഹപൂർവ്വം" (Sneha poorvvam) before signing off with your name.
