==== Structural differences ====
To refute Whorf's notion that structural categories correspond to symbolic categories, Lenneberg and Brown point out that structural categories rarely have consistent meanings. When they do, these meanings are not necessarily evident to speakers, as the case of grammatical gender in French illustrates. All French words with feminine gender do not reflect “feminine” qualities, nor do they share any common attributes. Lenneberg and Brown conclude that the existence of structural classes alone cannot be interpreted as reflective of differences in cognition.<ref name=":0" />
