Anti vs. Pro: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 21, 2023
'Anti' denotes opposition to or against something, while 'pro' indicates support for or favoring something.

Key Differences

'Anti' is used to express resistance or opposition to ideas, policies, or movements. 'Pro', conversely, is used to express approval or support for these entities.
In political or social contexts, 'anti' signifies being against a certain policy or ideology, like anti-war. 'Pro' in these contexts indicates advocacy or support, such as pro-democracy.
'Anti' can also denote prevention or counteraction, like in anti-theft. 'Pro', in contrast, often implies a proactive stance or promotion, as in pro-active.
The use of 'anti' suggests disagreement or a stance against something. 'Pro' suggests agreement or endorsement of an idea or cause.
'Anti' is fundamentally about negation or opposition, while 'pro' is about affirmation or support.
