Core Principle

No-equivalent sounds refer to English phonemes that do not exist or are not contrastive in a learner’s native language. Learners cannot rely on L1 spelling or sound analogies and must form a new grapheme–phoneme link directly in English.

Articulation Guide

For /v/: the upper teeth lightly touch the lower lip; airflow is continuous with vocal cord vibration. For /eɪ/: a diphthong gliding from mid-front to high-front, with the mouth moving from slightly open to narrower.

Word Analysis: vain

In vain /veɪn/, v lacks an equivalent in many languages and is often replaced by /w/ or /f/. Correct production requires friction plus voicing. The ai represents a full /eɪ/ glide, not a short vowel.

Pitfalls

Do not guess pronunciation from spelling alone. Do not reduce /v/ to /w/ or /f/, and do not shorten /eɪ/ to /e/. Sound awareness must precede spelling awareness.
