Formal:
* Naan bhojanam kazhikunno (നാന് ഭോജനം കഴിക്കുന്നു): This literally means "I am eating lunch" but is a more formal way to ask if someone has had lunch. You could add "kazhiyayoo" (കഴിച്ചയോ) at the end for a more direct "did you eat?"
* Bhojanam kazhikunno ennu chodichaanu (ഭോജനം കഴിക്കുന്നു എന്ന് ചോദിച്ചാണ്): This means "I asked if you had lunch."
Informal:
* Njangal kazhichoo (ഞങ്ങൾ കഴിച്ചു): This literally means "we ate." You can replace "njangal" (we) with "nee" (you) for a more direct "did you eat?"
* Lunch kazhiyayoo (ലഞ്ച് കഴിച്ചയോ): This is a more casual way to ask "did you eat lunch?"
Important Notes:
* The word for "lunch" in Malayalam is "bhojanam" (ഭോജനം).
* You can use the more formal "kazhikunno" (കഴിക്കുന്നു) or the more informal "kazhichoo" (കഴിച്ചു) depending on the context and your relationship with the person you are speaking to.
* Remember that Malayalam is a language with multiple dialects. The way someone says "had your lunch" might be slightly different depending on where they are from.
