What Is the Correct Plural of Antenna?

If we look at the root language, Latin, we can see why the plural form of the word antenna is antennae. However, if we are referring to the metal rod antenna it is instead correct to use the plural form antennas. 

The History and Origin of the Word

The word antenna originally comes from the Latin language. Its original definition in the Latin language is “sail yard”. 

The definition of a sail yard is “is a spar on a mast from which sails are set. It may be constructed of timber or steel or from more modern materials like aluminium or carbon fibre. Although some types of fore and aft rigs have yards, the term is usually used to describe the horizontal spars used on square rigged sails”

You might be wondering right now “how did we get our current definition of antenna from sail yard”. That is a pretty fitting question but it does have a fitting answer. The greek word for sail yard is “keraia”. It did mean sail yard but also meant horn (this was the main way that it was used in fact). Aristotle used the word keraia to refer to the antenna (feelers) of insects. He likely came to this usage based on how keraia would be the correct way to describe the horns of a larger animal. 

We still do use antenna to refer to the feelers of insects from the definition given to the word by Aristotle, but also we can use the same word to describe the kind of antenna we use to get signals. The likely reason for calling it an antenna is because it’s serving a similar function to an insect antenna. It is “feeling” the air for the signals passing through it, which is pretty much the same thing as an insect’s antenna.
