However, here are a few possibilities for what it might be called:
* मैकैडामिया (Makaidamiya): This is a simple transliteration of the English word.
* ऑस्ट्रेलियाई अखरोट (Australiaai Akharot): This means "Australian nut", as macadamia is native to Australia.
* चिड़िया नट (Chidiya Nut): This means "bird nut", which is a common name for macadamia in some other languages. However, this might be confusing with other small nuts in India.
Ultimately, the best way to understand what people call macadamia in Hindi would be to ask someone who is familiar with the nut.
