LowTechnical/Formal
Definition
Meaning
To make or treat as dual; to convert into, or operate with, a pair or two-fold structure.
In mathematics, computer science, and formal logic, to construct the dual of a given object, problem, or system (e.g., in linear programming, to convert a primal problem into its dual).
Linguistics
Semantic Notes
Primarily a technical verb with precise meaning in specialist domains. The process of dualization often implies a symmetrical or complementary relationship between the original and the dual form.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'дуэлизировать' (to duel) or 'удваивать' (to double). The closest equivalent is often a descriptive phrase like 'строить двойственную задачу'.
Common Mistakes
- Using 'dualize' to mean simply 'to double' or 'to duplicate' without the formal, symmetrical duality concept.
- Misspelling as 'duelize' (related to a duel).

FAQ
Frequently Asked Questions
No, it is a low-frequency, technical term used primarily in academic and specialist contexts.
It would sound very unnatural and would likely not be understood outside of specific technical discussions.
The related nouns are 'dualization' (the process) and 'duality' (the state or concept).
No. 'Duplicate' means to make an identical copy. 'Dualize' implies creating a complementary, often formally opposite, counterpart within a specific theoretical framework.
