Definition of alate in English:



Botany Biology
  • (chiefly of insects or seeds) having wings or winglike appendages.

    • ‘Adult shells of both C. syringothyriformis and species of Regelia are large with alate cardinal extremities and large nearly catacline ventral interareas.’
    • ‘Note that valve diameters do not include the alate longitudinal ridges.’
    • ‘Some possess wide ‘wings,’ or alate lamellae, while in other species the lamellae fold into delicate spines.’
    • ‘Ventral valve most strongly convex posteriorly, ventral deflection beginning at about 6 mm from beak, becoming slightly alate, but not preserved on anterior portion of valve.’
    • ‘Medium-sized, alate, subequally biconvex shells with deflected anterior margins in later growth stages.’


Mid 17th century: from Latin alatus, from ala wing.
