Research
In Aitchison (1987), she identifies three stages that occur during a child's acquisition of vocabulary: labelling, packaging and network building.

These stages are discussed in detail in surveys of theories of vocabulary acquisition such as Milton & Fitzpatrick (2014).
 * 1) Labelling: First stage and involves making the link between the sounds of particular words and the objects to which they refer, e.g., understanding that "mummy" refers to the child's mother.
 * 2) Packaging: Entails understanding a word's range of meaning.
 * 3) Network Building: Involves grasping the connections between words: understanding that some words are opposite in meaning, e.g., understanding the relationship between hypernyms and hyponyms.
