- Do not confuse with 'detect' (обнаруживать).
Common Mistakes
- Incorrect preposition: 'deter to do something' (correct: 'deter from doing something').
- Using as a direct synonym for 'stop' (deter implies discouragement, not absolute prevention).

FAQ
Frequently Asked Questions
'Deter' focuses on discouraging an action before it is attempted (through fear, cost, difficulty). 'Prevent' means to stop something from happening, often through direct intervention.
Rarely. It inherently involves creating a negative association (cost, risk, punishment) to discourage an action. The outcome (e.g., preventing a crime) may be positive, but the mechanism is negative.
The primary noun is 'deterrent'. 'Deterrence' is the abstract concept or policy of deterring.
It is always 'deter someone/something from doing something'. 'Deter to do' is incorrect.
