However, you can use a few options depending on the context:
* "பீகன் நட்ஸ்" (Pēkan natsu): This is a direct transliteration of the English "pecan nuts." It's the most common way to refer to pecans in Tamil.
* "பீகன்" (Pēkan): This is a shorter version, referring specifically to the pecan nut itself.
* "அமெரிக்க பருப்பு" (Amerikka paruppu): This translates to "American nut" and can be used if you're emphasizing the origin of the nut.
It's important to note that these are not traditional Tamil names and are primarily used in modern-day contexts.
If you're looking for a more traditional name, you might use a descriptive term like "நறுமணம் நிறைந்த பருப்பு" (narumanam niraindha paruppu), meaning "aromatic nut."
Ultimately, the best way to refer to pecans in Tamil will depend on the specific situation and the level of formality.
