When the vowel letter E is pronounced as/ε/in a closed syllable or in front of two identical consonants, the tip of the tongue should be flat against the lower teeth, the corners of the mouth should be widened to both sides, and the opening is slightly smaller than /a/. For example:

Sel salt

Seconds drying

Quayle, which one?

Cette this (indicating the feminine singular form of adjectives)

Termination (third person singular of termination)

Al, she

Celle this (feminine singular form of demonstrative pronoun)
