Step 1: Understanding Phonetic Classification.
In linguistics, sounds are categorized by their place of articulation, which is the location in the vocal tract where airflow is obstructed.
This question involves matching Khasi consonants to their respective phonetic categories.
Step 2: Explanation of Each Sound Group.
- (A) Nia, khlia, ain – Palatal: Produced by the tongue contacting the hard palate.
- (B) Pah, bam, mar – Bilabial: Articulated using both lips.
- (C) Kah, skum, suk – Velar: Produced at the soft palate near the back of the mouth.
- (D) Shah, kshald, shish – Alveo-palatal: Formed by the tongue simultaneously touching the alveolar ridge and the palate.
Step 3: Phonetic Accuracy.
The provided matches accurately reflect how Khasi phonemes correspond to general articulatory phonology principles.
This understanding is crucial for pronunciation, spelling, and phonetic transcription.
Step 4: Conclusion.
Therefore, the correct pairings are (A) - I, (B) - IV, (C) - II, and (D) - III.
