The term 'heartwood' is primarily used in forestry, woodworking, and carpentry contexts in both American and Brazilian cultures. In Brazil, 'cerne' is the standard technical term used in the timber industry, which is significant given Brazil's vast forest resources and major role in global timber production. The metaphorical use referring to the 'heart' or 'essence' of something is common in English literary and philosophical contexts but less frequent in Portuguese usage.
