    • n mentum The chin; the anterior and inferior part of the mandible or under jawbone of a mammal, with or without associated soft parts. It sometimes is regarded as including the parts in the whole interramal space, or interval between the horizontal rami of the mandible.
    • n mentum In entomology, the median or central and usually principal part of the labium. The term has been applied to different parts of the labium, in different insects and also in the same insect, whence confusion has arisen, especially in the use of the terms mentum and submentum. The mentum is properly the part of the labium between the submentum and the ligula, and is often less conspicuous than either of these. See labium, and cut at mouth-parts.
    • n mentum In botany, a projection in front of the flower in some orchids, caused by the extension of the foot of the column
