nk sound
Core Rule
The nk sound occurs when n + k form the phoneme /ŋk/. The letter n does not sound /n/; it shifts to the velar nasal /ŋ/ followed by the voiceless stop /k/. This pattern appears at word endings and within syllables.
Articulation Guide
Raise the back of the tongue to the soft palate for /ŋ/ while keeping the tongue tip relaxed. Air flows through the nose, then the tongue blocks and releases to produce a clean /k/ burst.
Word Analysis
- ink /ɪŋk/: short vowel plus classic /ŋk/ ending.
- extinction /ɪkˈstɪŋkʃən/: medial nk, smoothly linking /ŋ/ to /k/ and /ʃ/.
- pound /paʊnd/: contrast example; contains /nd/, not /ŋk/.
Pitfalls
Do not pronounce the n separately, and avoid confusing nk with ng (/ŋ/) or nd (/nd/) patterns.
Phonics Breakdown
Lift the tongue back for /ŋ/, then release quickly into /k/.
Sound Reference
- Practice /ŋ/ alone before adding /k/.
- Contrast ink vs. in to feel the nasal shift.
