Language Essentials for Teachers of Reading and Spelling (LETRS) Unit 2 Practice Test

When you attempt to articulate a nasal sound while pinching your nose, the sound cannot be produced. Nasal sounds, such as /m/, /n/, and /ŋ/, are characterized by the airflow through the nasal cavity, which is essential for their articulation. When you pinch your nose, you block the airflow that would typically go through your nasal passages, thereby preventing these sounds from being produced. This blockage effectively alters the necessary resonance and airflow patterns that define nasal consonants, making it impossible to articulate them clearly.

The other possibilities suggest outcomes that do not accurately reflect the nature of nasal sounds. For instance, amplification or maintaining the articulatory quality while blocking airflow is not feasible in the case of nasals. Similarly, nasal sounds will not transform into fricatives, which require a different articulatory setup that does not rely on nasal airflow. Thus, the conclusion is that pinching the nose leads to an inability to produce nasal sounds effectively.
