Consists of a number of converging ICM s which collectively give rise to a complex cluster which thus forms a stable large-scale model. The cluster model is held to be psychologically more complex than the individual ICMs which comprise it. According to who developed the notion of ICMs, the category mother is an instance of cluster model.

Lakoff suggests that the mother cluster model is made up of the following ICMs:

1. the birth model: a mother is the person who gives birth to the child.
2. the genetic model: a mother is the person who provides the genetic material for the child.
3. the nurturance model: a mother is the person who brings up and looks after the child.
4. the marital model: a mother is married to the child's father.
5. the genealogical model: a mother is a particular female ancestor.
