Step 1: Background on Dravidian languages.
The Dravidian language family is mostly concentrated in South India (Tamil, Telugu, Kannada, Malayalam, etc.) and parts of Central and Eastern India. However, one exceptional case is found outside India.
Step 2: Identify the outlier.
Brahui is a Dravidian language spoken in Balochistan, Pakistan, with around 2 million speakers. Its survival far from other Dravidian languages is a linguistic puzzle, sometimes explained as a remnant of earlier Dravidian distribution in the Indian subcontinent.
Step 3: Rule out the distractors.
- Konda, Kuvi, Toda — Dravidian languages, but all spoken in India (Andhra Pradesh, Odisha, and Tamil Nadu respectively).
- Only Brahui is spoken in Pakistan.
