Formal:
* இருக்கலாம் (irukkalām): This is the most common and versatile translation. It implies possibility or probability.
* நிகழலாம் (nigazhalām): This means "it could happen" or "it might occur."
Informal:
* ஒருவேளை (oruvelai): This is a more casual way to say "maybe" or "perhaps."
* சாத்தியம் (sathiyam): This literally means "possibility" and is often used in formal contexts.
Example sentences:
* He might be at home. (அவர் வீட்டில் இருக்கலாம்.)
* It might rain tomorrow. (நாளை மழை பெய்யலாம்.)
* Maybe she's right. (ஒருவேளை அவள் சரிதான்.)
* It's possible that he's lying. (அவர் பொய் சொல்லுவது சாத்தியம்.)
The best translation will depend on the specific situation and the level of formality you want to convey.
