What does elliptic mean?
Elliptic means relating to or resembling an ellipse — a closed oval curve — as when astronomers describe the paths planets trace around the sun. By extension, it also describes speech or writing that omits words understood from context: an elliptic remark says less than it means, leaving the listener to complete the thought. The word functions as an adjective and appears across mathematics, astronomy, and literary criticism. In everyday prose, its longer form 'elliptical' is more frequent, but 'elliptic' remains the standard choice in established technical terms such as 'elliptic curve' and 'elliptic geometry', branches of modern mathematics of great importance, notably in number theory and cryptography. Derived adverbial and alternative adjectival forms round out the family. Whether describing an orbit's shape or a speaker's studied brevity, elliptic conveys compression — a figure reduced to its essential outline, whether geometric or verbal.
Relating to or having the form of an ellipse; oval.
"The satellite settled into a stable elliptic orbit."
Preferred over 'elliptical' in fixed mathematical terminology.
(Of speech or writing) characterized by the omission of words understood from context; condensed or terse.
"His elliptic style rewards careful reading."
Mathematicians say 'elliptic curves' even though an ellipse is not actually involved — the name comes from the integrals used to study them.

Etymology of elliptic
Elliptic derives from Greek elleipein, meaning 'to fall short' or 'to leave out', via Latin ellipticus. It entered English in the early 17th century alongside related terms such as ellipse and ellipsis. The same Greek root also produced eclipse (an eclipsed celestial body 'falls short' of light), making these words true cognates.

How elliptic is actually used
In general usage, 'elliptical' is far more common than 'elliptic'; the shorter form survives mainly in fixed technical terms such as 'elliptic curve', 'elliptic function', and 'elliptic geometry'. Both forms share all senses.
Easily confused with elliptic
'Elliptical' is the more common everyday form of the same adjective, while 'elliptic' is preferred in technical mathematical contexts such as 'elliptic curve'.
