antennary

adjective anˈtɛnəriænˈtɛnəri

Zoology

Relating to or resembling antennae.
the existence of an antennary language among ants

Origin

Mid 17th century: from Latin, alteration of antemna 'yard' (of a ship), used in the plural to translate Greek keraioi 'horns (of insects)', used by Aristotle.

On old Mediterranean sailing ships certain types of triangular sail, called lateen sails, were supported by long yards or poles at an angle of 45 degrees to the mast, which reminded the ancients of an insect's antennae. The Latin word antenna was an alteration of antemna ‘sailyard’, and was used by writers to translate the Greek keraioi ‘horns of insects’. When Marconi and others developed radio in the 1890s the word was quickly taken up, along with aerial (see air), to refer to a rod or wire by which signals were received.
