labially造句

• On the dorsal surface of the dentary there is an interdental ridge that separates successive teeth labially.
• In the fourth cusp, the ridge hardly extends posteriorly, but rather labially, forming the posterior margin of the tooth and joining a ridge descending from the last labial cusp.
• This would appear to mean that is a more-or-less typical labio-velar approximant in most situations, with an unrounded semi-fricative allophone, approximately, before the vowel, though possibly a labially compressed velar in that environment.
