oblique section
C2Technical / Academic
Definition
Meaning
A cut or slice through an object at an angle that is not perpendicular to its main axis.
A representation or view of an object as it would appear if cut along a non-right-angle plane; used to reveal internal structure or features not visible in standard orthogonal views.
Linguistics
Semantic Notes
Primarily used in technical fields like engineering, anatomy, geology, and mathematics. Implies a deliberate, angled plane of intersection for analysis or representation.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Usage is identical across technical domains.

Virtually never used.
Academic
Used in technical papers, textbooks, and lectures in STEM fields to describe a specific method of dissection or graphical representation.
Everyday
Extremely rare. Would only be used when explaining a technical concept to a layperson.
Technical
Standard term in engineering drawings, anatomical studies, geological surveys, and computer-aided design (CAD) to specify a particular viewing plane.
Examples
By Part of Speech
verb
British English

Examples
By CEFR Level
- The teacher cut the fruit at an angle to show the children an oblique section.
- In the diagram, an oblique section of the hill shows the different layers of rock.

Learning
Memory Aids
Mnemonic
Think of slicing a baguette on a diagonal to get a longer, oval-shaped piece—that's an oblique section, not a straight-across slice.
Conceptual Metaphor
SEEING INSIDE FROM AN ANGLE (A perspective that reveals hidden aspects by not taking the direct, head-on approach).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'косое сечение' unless in a highly technical context where it is established. In many contexts, 'разрез под углом' or 'наклонное сечение' is more natural.
- Do not confuse with 'косой срез', which can imply a sloppy or imprecise cut in everyday language.
Common Mistakes
- Using 'oblique section' to mean a vague or indirect part of a written text (e.g., 'an oblique section of the report').
- Confusing it with 'cross section', which implies a perpendicular cut.
- Misspelling as 'oblike section'.

FAQ
Frequently Asked Questions
No. A cross section is typically a cut perpendicular to the long axis of an object. An oblique section is cut at any other angle.
It is a highly technical term. In everyday situations, you would simply say 'cut at an angle' or 'diagonal slice'.
To reveal internal structures or features that are not visible or are poorly defined in a standard perpendicular (cross or longitudinal) section.
No, that is a separate, figurative meaning. Here, 'oblique' uses its geometric meaning: 'slanting; at an angle that is not 90 degrees'.
