explement
C2 / Very LowTechnical / Specialised
Definition
Meaning
The quantity or angle that, when added to something, completes a full circle (360° or 2π radians).
In geometry, the explement of an angle is the difference between 360° and the given angle, representing the angle that 'wraps around' to complete the circle. In a more abstract sense, it can sometimes refer to a complement that fulfills or makes whole a larger system or conceptual whole, though this is rare and primarily metaphorical.
Linguistics
Semantic Notes
This term is almost exclusively used in specialised mathematical or geometric contexts. Its use outside of these fields is exceptionally rare and would be considered highly academic or deliberate stylistic choice.

Examples
By Part of Speech
adjective
British English
- The two angles are explementary.
American English
- The explementary angle is 225°.
Examples
By CEFR Level
- To find the explement, subtract your angle from 360 degrees.

Mnemonic
Think 'EXtra to comPLETE the circle'. EX-PL(E)MENT.
Conceptual Metaphor
COMPLETION IS A FULL CIRCLE
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'дополнение' (complement). The explement is specifically for a full 360°, while a complement is for 90° and a supplement is for 180°.
Common Mistakes
- Using 'explement' to mean a supplement (180° complement).
- Using the term in non-geometric contexts.

FAQ
Frequently Asked Questions
No, it is a highly specialised term used almost exclusively in geometry and trigonometry.
An explement completes a circle to 360°, while a supplement completes a straight line to 180°.
It would be highly unusual and likely confusing unless you were specifically discussing advanced geometry.
