nk sound

Rule Core

The nk sound occurs when n + k appear in the same syllable and are pronounced /ŋk/. The letter n does not keep /n/; instead, it assimilates to the velar nasal /ŋ/ before the voiceless velar stop /k/. This reflects a key English phonics principle: nasal assimilation.

Articulation Guide

Raise the back of the tongue to the soft palate to produce /ŋ/ with airflow through the nose. Then immediately block and release the air for /k/. Lips stay relaxed; the movement is smooth and continuous.

Word Analysis

• conjunction: the nk cluster is /ŋk/, never /n-k/.
• brandy: n is followed by d, so it stays /nd/—a useful contrast.
• bump: n becomes /m/ before p, showing how nasals change with following sounds, reinforcing the nk rule.

Pitfalls

Avoid pronouncing nk as two separate sounds, and do not confuse nk with ng, which usually lacks a final stop.
