母音

1. Origins, structure, and basic meaning

• Structure: 母音 (ぼいん) is a vowel produced without major obstruction of airflow. 母音を発音する makes it a pronunciation target; 母音が異なる makes it a compared feature.
• Basic usage: Vowels are pronounced slowly after a teacher; the initial vowels of two words differ.

2. Common pitfalls and similar expressions

• Sound practiced and initial sound distinguishing words
  • The first takes multiple vowels as objects; the second makes each word's first vowel the subject. Its articulation differs from consonant 子音.
