/ g / ▼ ▼ [ g<w ] [ g>w ] gad dag The soft palate being raised and the nasal resonator shut off, the primary obstacle to the air-stream is formed by a closure made between the back of the tongue and the soft palate. Lung air is compressed behind this closure, during which stage the vocal folds may vibrate for all or part of the compression stage for / g / according to its situation in the utterance. The lip position will be conditioned by that of adjacent sounds, especially following vowels, e.g. spread lips for the plosives in geese, geezer and somewhat rounded lips for the plosive in goose, Guatemala. The air escapes upon the sudden separation of the lingua-velar closure. The velar stop contact is particularly sensitive to the nature of an adjacent vowel. Thus, when a front vowel follows, e.g. / g / in geese, the contact will be made on the forward part of the soft palate. When a back vowel follows, e.g. gone, the contact on the soft palate will be retracted.

The soft palate being raised and the nasal resonator shut off, the inner surface of the lower lip makes a light contact with the edge of the upper teeth, so that the escaping air produces friction. The actual point of contact will vary somewhat according to the adjacent sound, e.g. in the case of a back rounded vowel as in fool, roof, the contact on the lower lip tends to be more retracted than in the case of a front spread vowel in feel, leaf. The friction is voiceless.

DRILL 30 LOSS OF PLOSION* ▼ [ {p×t ] [ eb×d ] apt ebbed It is a feature of English that in a cluster of two stops (plosives or plosive + affricate) either within a word or at word boundaries, the first plosive has no audible release. The closure for the second stops is made before the release of the first, forming a further obstacle to the air-stream.
*See the rule on page 25, IV b. DRILL 31 LATERAL PLOSION* ▼ ▼ ▼ ▼ ▼ ▼ [ p×l□ ] [ t×l□ ] [ k×l□ ] [ b×l ] [ d×l ] [ g×l ]
The most frequent tongue contact for English / l / being alveolar, the sequences / t / or / d / + / l / are homorganic. / t / and / d / in such situations are normally released laterally, i.e. one or both sides of the tongue are lowered to allow the air to escape, the tongue-tip contact remaining. Such homorganic lateral release is to be distinguished from sequences of /p, b, k, g/ + / l /, e.g. in apple, bubble, tackle, glow. In these cases, the partial alveolar contact for / l / is made before or at the time of the release of the plosive, and in this sense, the escape of air is lateral.

A different kind of nasal release occurs when the nasal sonant following a plosive is not homorganic, e.g. abnormal, ignore, cheap nuts, bad man. In these cases the plosive closure is not normally released until the articulatory movements for the nasal consonant, i.e. the second oral closure and the lowering of the soft palate, have been accomplished.
