Developing TREE’s organisational framework for clear and inclusive language
Summary:
In December 2025 TREE released Version One of the Words Matter Framework. This institutional guide sets out TREE’s terminology standards for discussing Britain’s history of enslavement, its legacies and the communities connected to these histories. The framework responds to growing requests from schools, broadcasters and heritage organisations for reliable, evidence based language guidance.
The Challenge:
Many public bodies and educators continue to rely on outdated, imprecise or inconsistent language when discussing the history of enslavement. Some commonly used terms carry harmful or misleading connotations. TREE identified a need for a framework grounded in archival evidence, academic research and inclusive practice that prioritises clarity and dignity.
TREE’s Role:
TREE undertook a detailed review of:
Terminology used in its own archive and education materials
Museum guidance and national policy standards
Language used by schools, researchers and broadcasters
Community expectations around representation and accuracy
TREE then produced a structured terminology guide that defines recommended language, explains why certain terms should be avoided, and supports users in navigating sensitive historical contexts.
The Evidence:
The framework draws on:
Primary documents from TREE’s archive
Academic scholarship in British colonial history
Office of National Statistics (ONS) and relevant UK government guidance
Museum sector terminology reviews and practice notes
Outcomes and Impact:
The Words Matter Framework has since been used informally by several schools and heritage organisations. A national broadcaster sought TREE’s guidance while preparing a public communication on enslavement, demonstrating the relevance and authority of the framework. It now forms part of TREE’s core offering to partners.
Next Steps:
TREE will expand the framework in early 2026, aligning it with the Words Matter Campaign and supporting wider sector learning.
