Contextual explanation: Political-economic ideology prioritising market mechanisms.
Neoliberalism is best understood as a political and economic ideology that emphasises the primacy of free markets, competition, privatisation, deregulation, and minimal government intervention in economic affairs. It shapes how societies organise economic activity and influences policy decisions at both national and global levels.

Themes: Market-driven governance and economic policy. 
The theme central to neoliberalism is the reliance on market mechanisms to allocate resources and drive economic growth. This theme is relevant because it underpins policy shifts towards deregulation, privatisation of public assets, and reduced state involvement in economic management, affecting social welfare, labour relations, and public services.

Nuance: Emphasis on individual responsibility and competition. 
What distinguishes neoliberalism within its category is its focus on individual responsibility, entrepreneurialism, and competition as the primary drivers of prosperity and social order. This nuance sets it apart from other economic or political ideologies that may prioritise collective welfare, state intervention, or social equity.
