Final answer:
The Nairs or Nayars are from the Malabar Coast of Kerala, situated on the southwestern coast of India, which is on the western side of the country along the Arabian Sea.
Step-by-step explanation:
The Nairs, also known as Nayars, are a group that traditionally hail from the Malabar Coast in the southwest region of India, specifically in the state of Kerala. This area is well known for its beautiful coastline along the Arabian Sea and is steeped in history with various cultural influences. Cities such as Kozhikode (formerly known as Calicut) are located in this region. When considering the navigational division of India, it can be done so along north/south dimensions, with the Malabar Coast being in the southern part of the country. Similarly, east/west divisions place the Malabar Coast on the western side of the Indian subcontinent, alongside the Arabian Sea.
