However, depending on the context, it could be translated as:
* "Groundnut": This is the most common translation, as Thattampayir refers to the peanut plant and its fruit.
* "Peanut": This is another common translation, referring to the edible seed itself.
* "Peanut Butter": If the context is about the paste made from ground peanuts, then this is the appropriate translation.
To provide a more accurate translation, you need to provide more context. For instance:
* What is the specific context you are referring to?
* What is the sentence or phrase where "Thattampayir" is used?
Once you provide more details, I can offer a more precise translation.
