Meronyms (Component Parts)

Meronyms are component parts of entities: 'keyboard' is a meronym of 'laptop', 'engine' is a meronym of 'car'. In semantic SEO, meronyms build content completeness (Topical Coverage); an article about cars without meronyms ('car is a vehicle, cars are popular') won't be cited as an expert source, while an article with meronyms ('a car consists of internal combustion/electric engine, manual/automatic transmission, suspension...') AI recognizes as complete and authoritative.

Meronyms reveal entity attributes to cover in content — each component part is a potential sub-query with fan-out and a potential H3 heading.

In practice, for each Central Entity list 5-10 meronyms using lexical expansion tools and check which ones competitors cover. Missing meronyms are your Information Gain. Meronyms directly connect to the EAV model: each component part is an attribute of the entity with concrete values that AI can cite.
