Another set of concepts related to fuzziness in semantics is based on
prototypes. The work of Eleanor Rosch and George Lakoff
in the 1970s led to a view that
natural categories are not characterizable in terms of
necessary and sufficient
conditions, but are graded (fuzzy at their boundaries) and inconsistent as to
the status of their constituent members.

Systems of categories are not objectively "out there" in the world but are
rooted in people's experience. These categories evolve as learned concepts
of the world — meaning is not an objective truth, but a
subjective construct, learned from experience, and language arises
out of the "grounding of our
conceptual systems in shared embodiment and bodily experience".
A corollary of this is that the conceptual categories
(i.e. the lexicon) will not be identical for
different cultures, or indeed, for every individual in the same culture. This
leads to another debate (see the Whorf-Sapir hypothesis or Eskimo words for snow).

English nouns are found by language analysis to have 25 different semantic features, each associated with its own pattern of fMRI brain activity. The individual contribution of each parameter predicts the fMRI pattern when nouns are considered thus supporting the view that nouns derive their meaning from prior experience linked to a common symbol.
