A generally accepted view regarding proper names is that they have reference, but no lexical meaning (Lyons, 1977). This idea is the basis for the Functional Discourse Grammar (Hengeveld & Mackenzie, 2008) view of proper names as primitives of the Interpersonal Level and the lexical head of Subacts of Reference. At the Representational Level, the entity is designated by an absent head, which captures the fact that proper names do not have a meaning. Although this approach accounts for the most prototypical use of proper names, it fails to explain a range of other uses. In addition to the referential use of non-modified proper names, this paper analyses other uses of proper names in Portuguese: modified proper names, metaphorical proper names, and proper names in naming constructions. The proposal presented here explains cases of restrictive modification and metaphorical uses of proper names as instances of reflexive language and coercion, respectively. As for proper names in naming constructions, they are considered to have a third, different, function, in addition to the vocative and referential use.@font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Times;panose-1:0 0 5 0 0 0 0 2 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:-536870145 1342185562 0 0 415 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin:0in;mso-pagination:none;text-autospace:none;font-size:11.0pt;font-family:"Times New Roman",serif;mso-fareast-font-family:"Times New Roman";mso-ansi-language:EN-US;mso-fareast-language:EN-US;}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-size:11.0pt;mso-ansi-font-size:11.0pt;mso-bidi-font-size:11.0pt;font-family:"Calibri",sans-serif;mso-ascii-font-family:Calibri;mso-ascii-theme-font:minor-latin;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-font-family:Calibri;mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi;mso-ansi-language:EN-US;mso-fareast-language:EN-US;}.MsoPapDefault{mso-style-type:export-only;mso-pagination:none;text-autospace:none;}div.WordSection1{page:WordSection1;}
