Diu Indo-Portuguese features a particular type of plural which may be termed associative plural according to the criteria of referential heterogeneity and reference to groups, but which in fact transcends the semantics of an associative plural. This particular construction circumscribes the referential potential of the NP not so much to elements associated to a given prominent member of the group but rather to elements sharing (a) certain feature(s) with a standard. This construction is therefore most properly termed a similative plural. Its translation equivalent is not necessarily 'X and associates' but rather 'X and people/things like X'.
The similative/associative plural involves the same marker of additive plurality, viz. tud (also a universal quantifier), although in a different position relative to the head noun. Whereas tud precedes the head noun in additive plural reference, it occurs immediately after the noun in a similative/associative plural.
