Etymology
The English word 'wafer' entered the language in the late 14th century from the Anglo-French 'wafre' and Old North French 'waufre', which itself came from a Frankish source. This Frankish word is related to the Middle Dutch 'wafel' and Old High German 'waba', meaning 'honeycomb', a term which shares a Proto-Indo-European root meaning 'to weave'. The semantic connection is clear: the earliest wafers, baked between patterned irons, had a surface texture resembling a woven honeycomb. Over time, the meaning generalized to any thin, crisp cake, and later specialized in religious and technological contexts, while retaining the core idea of a thin, flat object.
