Formal:
* அம்மா (amma): This is the most common and formal way to say "mother." It's used in all situations where you need to address your mother respectfully.
Informal:
* அம்மா (amma): This is still the most common way to say "mother" even in informal settings.
* அம்மை (ammai): This is a slightly more affectionate and informal way to say "mother" but is less commonly used than "amma."
Other Options:
* தாய் (thāy): This is a more literary and poetic way to say "mother." It's often used in writing and songs.
Note: The pronunciation of "amma" is similar to "uh-muh."
So, the best way to write "mother" in Tamil depends on the situation and your relationship with the person you are talking about.
