Vowels are produced with total closure of the oral cavity, causing a burst of air upon release.

Vowels in English are always classified based on their grammatical function in the sentence.

Vowels occur only when the vocal cords vibrate without any influence from tongue or lip position.

Vowels are classified according to tongue height, tongue position, and lip rounding during articulation.

Consonants are produced with continuous airflow through an open vocal tract.

Consonants involve obstruction or constriction of airflow at specific points of articulation.

Consonants are defined solely by the vibration of the vocal cords without influence of articulation points.

Consonants are classified based only on their position in the word, not on articulation features.

Two-syllable adjectives commonly follow the same stress pattern as two-syllable nouns, with stress on the first syllable.

In English, word stress placement always corresponds directly to the longest syllable phonetically.

Stress in English words is assigned randomly without consistent patterns across word categories.

Two-syllable nouns typically have stress on the second syllable.

A phoneme is a concrete realization of a sound, while an allophone represents an abstract category of sounds.

A phoneme represents a minimal sound unit that differentiates meaning, and an allophone is a contextual variation of this unit.

A phoneme is always produced exactly the same way regardless of its position in a word.

An allophone is responsible for changing the meaning of words by itself in all communicative contexts.
