Analyses of suicide notes have been conducted from varied perspectives in both linguistics and psychology. Not only have these studies added considerable value to the study of suicide, but they have also enriched the field of forensic linguistics. By analysing suicide notes, researchers are able to speculate about the state of mind of a suicidal individual from a psychological perspective, as well as gain insights into the characteristics of this genre from a linguistic perspective. Studies of suicide notes that are most relevant to forensic linguistics are those that compare authentic and fabricated suicide notes to determine whether these types of suicide notes may be distinguished from one another. Although the literature on suicide notes includes multiple studies that consider the differences between authentic and fabricated suicide notes, none seems to consider the fact that there might not be distinct differences between these types of suicide notes. Past studies also do not seem to consider that it might not be possible to determine whether a single suicide note is authentic or not. The present study fills this gap by considering authentic and fabricated suicide notes as indistinguishable texts. In this study, appraisal theory is used as the main theory of linguistic analysis to prove that authentic and fabricated suicide notes do not have distinct linguistic characteristics that can be used to differentiate them and that aiming to authenticate suicide notes might be a very risky and problematic undertaking. The results indicate that based on the theories and methods discussed in this thesis, it is not possible to successfully distinguish between authentic and fabricated suicide notes. It appears that, overall, the suicide notes included here would be more suited to analyses aimed at determining authorship identification or verification than analyses aimed at authenticating suicide notes. Accordingly, the study contributes not only to research concerned with the analysis of suicide notes but also to that concerned with forensic linguistics. Furthermore, the study includes analyses of South African suicide notes, and specifically Afrikaans suicide notes, which has not been attempted in previous research. / Tshekatsheko ya mangwalo ao a ngwadilwego ke batho ba go ipolaya e dirilwe go tswa mahlakoreng ao a fapanego ka go bobedi dithutapolelo le dithutamahlale tsa menagano.

Izifundo zocwaningo azikhulisanga kuphela ukubaluleka kocwaningo olumayelana nokuzikhunga kuphela, kodwa ziphinde zanothisa umkhakha weforensiki yelingwistiki. Ngokuhlaziya amanothi amayelana nocwaningo, abacwaningi bayakwazi ukwenza umhlahlo ngesimo somqondo womuntu ozikhungayo ngokomqondo wezengqondo, kanye nangokuzuza ulwazi olumayelana nezimpawu zalo mkhakha ngokomqondo welingwistiki. Izimfundo ezimayelana namanothi ashiywa ngabantu abazibulalayo ahlobene kakhulu neforensiki yelingwistiki yilawo aqhathanisa amanothi okuzibulala oqobo nalawo angamanothimbumbulu, ukucacisa kahle ukuthi mhlawumbe lezi zinhlobo zamanothi angahlukaniswa kwamanye. Yize umbhalo wobuciko omayelana namanothi okuzibulala axuba izimfundo zocwaningo eziningi ezigxile kwimehluko ephakathi kwamanothi okuzibulala oqobo nalawo okuzakhela/ambumbulu, akhekho obheka udaba lokuthi kungahle kungabi khona umehluko ogqamile phakathi kwalezi zinhlobo zamanothi okuzibulala. Izimfundo zocwaningo zesikhathi esedlule nazo azilubheki udaba lokuthi angekhe kwenzeka ukuthi kutholakale ukuthi mhlawumbe inothi lokuzibulala ngabe elangempela noma yinothimbumbulu. Isifundo samanje sivala lesi sikhala ngokuthatha amanothi angempela namanothimbumbulu njengemibhalo engahlukaniseki. Kulesi sifundo socwaningo, ithiyori yokuhlola isetshenziswe njengethiyori eyinsika yokuhlaziya ilingwistiki ukukhombisa ukuthi amanothi okuzibulala angempela nalawo okuzakhela akanazo izimpawu ezibaphawulekayo ezingasetshenziswa ukuwehlukanisa kanti lokho kuqonde ukuqinisekisa ukuthi amanothi okuzibulala kungenzeka abe wumsebenzi onobungozi obukhulu kanye nenkinga enkulu. Imiphumela ikhombisa ukuthi ngokwamathiyori nangezindlela ezixoxwe kule thiyori, kunzima ukuphumelela uthole umehluko phakathi mwamanothi angempela nalawo ambumbulu. Ngaphezu kwalokho, kuyakhombisa ukuthi, amanothi okuzibulala aqukethwe lapha azohambisana kakhulu nolwazi oluhlaziyiwe oluqonde ukuthola umnini wenothi noma ukuqinisekisa kunolwazi oluhlaziyiwe oluhlose ukuqinisekisa umbhali wamanothi okuzibulala. Ngokosiko lwakhona, isifundo asifakanga kuphela igalelo kucwaningo kuphela ngokuhlaziya amanothi okuzibulala, kanti lokho futhi kumayelana neforensiki yelingwistiki. Ngaphezu kwalokho, ucwaningo luqukethe ulwazi oluhlaziyiwe lwamanothi okuzibulala eNingizimu Afrika, ikakhulu amanothi okuzibulala abhalwe ngesiBhunu, angakazwe alokothwe kucwaningo lwesikhathi esedlule. / Linguistics and Modern Languages / Ph.
