What does afforest mean?
To afforest is to turn land that was not previously woodland into forest, typically by planting trees or sowing tree seed across a substantial area. The word belongs chiefly to the language of forestry, ecology, and environmental policy, where it carries a deliberately technical tone: officials, conservationists, and land managers use it when describing large-scale schemes to create new woodland on moorland, grassland, degraded farmland, or other open terrain. It is closely related to — and often contrasted with — reforestation, which restores forest on land that was once wooded but has been cleared. Afforestation projects are frequently tied to goals such as carbon sequestration, flood mitigation, biodiversity recovery, and timber production, which gives the verb a broadly positive, purposeful connotation. Though uncommon in casual conversation, afforest is a precise and useful term for anyone writing about climate policy, land use, or ecological restoration.

Afforest doesn't just mean planting trees — it specifically means turning never-forested land, like open moor or scrubland, into brand-new woodland.

Etymology of afforest
Afforest derives from Latin silva (forest) via the medieval Latin noun foresta, which entered Old French as foret and Middle English as forest. The verb was formed in English in the early modern period from the prefix af- (a variant of ad-, meaning 'to' or 'toward') combined with forest, literally meaning 'to make into forest'. It shares its root with related terms such as forestry, forester, and reforest.
