Classification paragraphs — those that introduce a general category and then list its members or sub-types — are among the most common organisational patterns in academic writing, yet students routinely fail to recognise them. When no pronouns, articles, or connectors provide a grammatical foothold, the logical architecture of the paragraph becomes your only guide. This chapter trains you to see paragraphs as taxonomic structures: a category sentence that names the class, followed by member sentences that enumerate its instances.
By the end of this chapter, you will be able to identify category-introducing sentences, recognise explicit enumeration markers and parallel grammatical structures, and use these patterns to reconstruct the correct order of classification and enumeration paragraphs.

Academic writers almost universally place the general category statement before the specific instances that illustrate it. The category sentence names or defines a class — using phrases like 'several types of,' 'classify according to,' or 'comprises distinct classes' — while the member sentences each describe one instance of that class. This ordering reflects the logical principle of moving from general to specific, which is deeply embedded in academic prose conventions. If one sentence names a category and another sentence is clearly a member of that category, the category sentence must come first, regardless of whether any explicit transition word signals the relationship.
The sentence that names the category is the structural anchor; every sentence that describes a specific instance of that category must follow it.
Students sometimes place a vivid or detailed member sentence first because it feels more concrete and informative, overlooking the fact that the category framework must be established before its members can be meaningfully enumerated.

In a monopoly, a single firm dominates the entire market, setting prices without competitive pressure.
Perfect competition, in which numerous small firms sell identical products, represents one extreme of this spectrum.
Between these poles lie oligopoly and monopolistic competition, each with distinct strategic implications for pricing and output.
Economists classify market structures according to the number of firms, product differentiation, and barriers to entry.

Dismissive-avoidant individuals suppress emotional needs and maintain a superficially self-sufficient exterior.
Attachment theory identifies several primary styles that shape how individuals approach intimate relationships throughout adulthood.
Securely attached individuals, who typically had responsive caregivers in infancy, tend to form stable, trusting relationships.
Those with a fearful-avoidant style simultaneously desire and fear closeness, resulting in erratic relational behaviour.

Rhyolite, which forms from rapidly cooled felsic magma, is characterised by a light colour and fine-grained texture.
Basalt, produced by the solidification of mafic lava at the surface, is the most abundant volcanic rock on Earth.
Andesite, which has an intermediate silica content, is commonly associated with subduction zone volcanism.
Volcanic rocks are classified primarily by their chemical composition, which determines both texture and mineral content.

When multiple sentences enumerate members of the same category, they frequently adopt parallel grammatical forms — identical sentence openings, repeated syntactic templates, or explicit enumeration markers such as 'the first,' 'a second,' 'another,' 'a third.' These markers function as an implicit numbered sequence within the paragraph. Even when no explicit numbers appear, parallelism between sentence openings signals that the sentences occupy the same structural level and should be read in the order they appear. Recognising this parallel architecture allows you to sequence member sentences even when you do not fully understand the technical content.
Parallel sentence openings create an implicit numbered list; the grammatical repetition itself is the ordering signal.
Students overlook implicit parallelism — two or more sentences sharing identical syntactic form without explicit 'first,' 'second' markers — and instead attempt to order member sentences by content difficulty or sentence length, which has no reliable relationship to paragraph position.

Another is the tendency for firms to collude rather than compete.
Oligopolistic markets exhibit several distinctive characteristics.
One such characteristic is the presence of significant barriers to entry that protect incumbent firms.
