Antennae vs. Antennas – Which is Correct?
Both antennae and antennas are correct plural forms of the word ‘antenna’. While ‘antennas’ is the more common and preferred plural for electronic devices and general usage in American English, ‘antennae’ is the traditional Latinate plural, often used for biological feelers of insects and sometimes in more formal or scientific contexts for devices. Both are grammatically sound.
Antennae or Antennas – Which is Correct?
The good news is that both antennae and antennas are considered correct plural forms of the noun ‘antenna’. However, their usage often carries subtle distinctions, particularly in modern American English. Antennas is the regular English plural, formed by adding ‘-s’ to the singular noun. It is widely used for referring to electronic devices that transmit or receive radio waves, such as those on a car, a radio, or a cell tower. It is also increasingly accepted as a general plural for all contexts, including biological ones. Antennae, on the other hand, is the traditional Latinate plural, reflecting the word’s origin. It is commonly reserved for the biological feelers of insects and other arthropods. While it can also refer to electronic devices, this usage is less common today compared to ‘antennas’ for technology.
The Best Trick to Remember the Difference
To easily remember the common distinction, think of it this way:
- Antennas: Associate this with Technology. Think of radio antennas, TV antennas, or car antennas. The ‘s’ ending connects to modern, systematic technology.
- Antennae: Associate this with Insects. Think of the delicate feelers on an ant or a butterfly – their antennae. The ‘ae’ ending gives it a more classical, biological feel.
While both are valid, using ‘antennas’ for devices and ‘antennae’ for insects is a simple way to navigate the most common preferences.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| antennae | Noun (plural) | Plural of ‘antenna’, often for insect feelers or traditional/formal contexts. | The moth waved its delicate antennae in the dark. |
| antennas | Noun (plural) | Plural of ‘antenna’, primarily for electronic devices; also acceptable for biological. | We need to adjust the satellite antennas for better reception. |
How to Use Antennae
The plural form antennae is derived directly from Latin, where ‘antenna’ is a feminine noun of the first declension, forming its plural with ‘-ae’. In English, its use often signals a more traditional, scientific, or formal tone. It is most frequently encountered when referring to the sensory appendages of insects, crustaceans, and other arthropods. For example, entomologists consistently use ‘antennae’ to describe these biological structures. Historically, ‘antennae’ was also the standard plural for technological devices, but this usage has largely shifted towards ‘antennas’ in contemporary English, especially in casual and technical contexts related to electronics.
Example 1: The beetle’s long antennae twitched, sensing vibrations in the air.
Example 2: Scientists observed the intricate movements of the crab’s antennae as it navigated the seafloor.
Example 3: In older scientific texts, one might find references to radio receiver antennae, though ‘antennas’ is now more common.
What are the different forms of Antennae?
Antennae is already a plural form. The singular form is antenna. The plural ‘antennae’ is an irregular plural in English, following its Latin origin.
- Singular: antenna
- Plural (Latinate): antennae
There are no other grammatical forms (like tenses or degrees of comparison) for this noun.
Etymology of the word Antennae
The word ‘antenna’ comes from Latin, meaning ‘sail yard’ or ‘spar’. It was later adopted into zoological terminology in the 17th century by naturalists to describe the sensory appendages of insects, possibly due to a perceived resemblance to a ship’s rigging. The plural ‘antennae’ directly reflects this Latin origin.
How to Use Antennas
The plural form antennas is the regular English plural, formed by simply adding ‘-s’ to the singular noun ‘antenna’. This is the prevailing and most commonly accepted plural form, particularly when referring to electronic devices that transmit or receive electromagnetic waves. This includes everything from the small internal antennas in smartphones to large parabolic satellite dishes. Its usage is widespread in engineering, telecommunications, and everyday conversation. While it is the standard for technology, ‘antennas’ is also perfectly acceptable when referring to biological feelers, and its use in this context is becoming increasingly common, blurring the traditional distinction.
Example 1: The house has several TV antennas on the roof for different channels.
Example 2: Modern cell towers are equipped with multiple antennas to handle high volumes of data traffic.
Example 3: The grasshopper’s antennas vibrated as it searched for food, though ‘antennae’ is also common here.
What are the different forms of Antennas?
Antennas is already a plural form. The singular form is antenna. The plural ‘antennas’ is a regular English plural, formed by adding ‘-s’ to the singular noun.
- Singular: antenna
- Plural (Regular English): antennas
There are no other grammatical forms for this noun.
Etymology of the word Antennas
Like ‘antennae’, ‘antennas’ traces its root to the Latin ‘antenna’. However, the plural ‘antennas’ represents the Anglicized, or regularized, plural form, adapting the word to standard English pluralization rules rather than retaining its original Latin inflection. This regularization occurred as the term became more widely used, especially in technological contexts.
Related Concepts
Understanding a few broader grammatical concepts can help clarify why words like ‘antenna’ have multiple correct plural forms in English.
- Latin Plurals in English: English has borrowed many words from Latin, and some retain their original Latin plural forms, such as ‘alumnus’ (alumni), ‘datum’ (data), and ‘cactus’ (cacti/cactuses). ‘Antennae’ is an example of such a retained Latin plural.
- Regular vs. Irregular Plurals: English nouns typically form their plural by adding ‘-s’ or ‘-es’ (regular plurals, like ‘cat’ to ‘cats’, ‘box’ to ‘boxes’). Irregular plurals either change their spelling significantly (‘man’ to ‘men’, ‘mouse’ to ‘mice’) or retain foreign pluralizations (‘criterion’ to ‘criteria’, ‘antenna’ to ‘antennae’). In many cases, like ‘antenna’, both the foreign plural and a regular English plural exist and are accepted.

Frequently Asked Questions
Question 1: Is “antennae” only used for insects?
While “antennae” is predominantly used for the sensory organs of insects and other arthropods, historically it was also used for technological devices. However, in contemporary American English, “antennas” is now the more common and preferred plural for electronic equipment.
Question 2: Which plural form is more common in general usage?
“Antennas” is generally more common in everyday language and for technical contexts involving electronic devices. “Antennae” retains a more formal, scientific, or traditional tone, especially in biological contexts.
Question 3: Can the singular “antenna” refer to both insect feelers and electronic devices?
Yes, the singular “antenna” is universally accepted for both meanings. The distinction in plural forms (“antennae” vs. “antennas”) primarily reflects historical linguistic preferences and common usage patterns rather than a strict difference in the singular noun’s meaning.
Conclusion
In the debate between antennae and antennas, both forms are grammatically correct plurals of ‘antenna’. The choice often boils down to context and convention. While antennas has become the standard and most widely accepted plural for electronic devices and general usage in American English, antennae maintains its traditional role, particularly when referring to the biological sensory organs of insects. Understanding this nuance allows for precise communication, whether you’re discussing the latest in telecommunications or the fascinating world of entomology.
Pro Tip: When in doubt, especially in technical or journalistic writing, opt for antennas for devices, as it’s the more common and less formal choice. Using the appropriate plural can subtly enhance your professional reputation and ensure clarity for your audience.
