Thing that discourages an action
Something that makes people not want to do something.
Usage pattern:
[something] is a deterrent to/against [action]
Common mistake:
Learners sometimes confuse the noun 'deterrent' with the verb 'deter'. Use 'deterrent' as a thing: 'This law is a deterrent to crime.' Use 'deter' as a verb: 'This law deters crime.' Also, the common prepositions are 'to' and 'against': 'a deterrent to crime', 'a deterrent against theft', not 'a deterrent for crime' in standard usage.
Synonyms
disincentive (Often used for financial or policy-related things that reduce motivation.)
|
discouragement (More general and emotional; not always about stopping a specific action.)
|
hindrance (Focuses on making something harder rather than on changing someone’s decision.)
Antonyms
incentive (Something that makes people more likely to do something, often through reward.)
|
encouragement (Emotional or verbal support that makes someone want to do something.)

Preventing or discouraging something
Able to stop or reduce an action by making people afraid or unwilling to do it.
Usage pattern:
deterrent [noun]
Common mistake:
Learners sometimes say *'very deterrent'* instead of using it with a noun, as in 'a strong deterrent effect' or 'highly deterrent measures'. 'Deterrent' is usually followed by a noun (effect, measures, policy) rather than used alone like 'good' or 'bad'.
Synonyms
discouraging (More general and emotional; not always linked to rules or punishment.)
|
preventive (Focuses on stopping something before it happens, often in medical or policy contexts.)
Antonyms
encouraging (Makes an action more likely instead of less likely.)
|
permissive (Allows actions easily, giving little or no attempt to stop them.)

Military power preventing enemy attack
The military power, especially nuclear weapons, that a country keeps to stop other countries from attacking it.
Usage pattern:

Synonyms
military deterrent (More explicit about the military nature; otherwise the same basic idea.)
|
defensive capability (Broader; includes general defense, not only the power to frighten enemies.)
Antonyms
disarmament (The reduction or removal of weapons instead of keeping them as a threat.)
|
vulnerability (A state of weakness that invites attack rather than deterring it.)
