With the boom in Indo-European (IE) studies among linguists from the early 20th century, toponymic studies on European place names have been largely based on the Proto-Indo-European (PIE). However, historical and archaeological records of non-IE groups, such as the Nuragic civilization of Sardinia, have presented the possibility of pre-IE/non-IE (Paleo-Sardinian) linguistic stratum influences on certain toponyms in Sardinia, Italy. This article aims to present a meta-study on existing toponymic reconstructions theorized by scholars, while offering a fresh perspective by employing methods of historical phonetic chains and sequences analysis to identify toponyms of interest. Analysis showed that certain Sardinian toponyms contain striking phonetic sequences that are uncharacteristic of PIE, such as *s(a)rd-, *kar-, *-ini, *-ài/*-éi, *#[θ]-. Overall conclusions appear to display the merits of (1) PIE and (2) pre-IE/ non-IE theories. Both provide plausible toponymic reconstructions. (1) The accuracy of IE theories is brought into question, as they appear to rely heavily on phonetic links to existing PIE roots, sometimes with a lack of consideration for other contextual or hydro-geo-morphological factors. (2) Conversely, pre-IE/non-IE theories are found to be highly speculative due to the lack of historical data, and knowledge, about the Paleo-Sardinian language.

This article studies and provides a narrative review of the history of the native Orang Kallang people residing on Singapore’s Kallang River before Singapore’s modernization. The first section delves into the Orang Laut and how a group of them moved to the Kallang River to form the independent tribe of the Orang Kallang. This is followed by the historical significance of the Kallang River and its role in trade and maritime commerce in early Singapore. Subsequently, the second section investigates the Orang Kallang’s origins, livelihood, language, and reasons for their eventual decline. As the Orang Kallang tribe split after the arrival of the British in 1819, the group that settled in Pulai River, Johor, was recorded to have dwindled staggeringly in population due to a smallpox epidemic. The third section will focus on the impact of smallpox on the early aboriginal populations of Singapore (and the overarching region of Malaya), failed vaccination attempts, and how the Orang Kallang was likely to have been impacted. The last section will sum up the themes discussed in the paper.

At the eastern entrance of the Singapore Strait lies Pedra Branca, an island of granite rock situated in hazardous waters. Its unexceptional presence belies a rich cartographical history and infamous reputation for leading ships to grief since antiquity. Pedra Branca was first pushed into the spotlight when the British constructed the Horsburgh Lighthouse in 1851. It later caught international attention when a heated territorial dispute for the island between Singapore and Malaysia arose, lasting from 1979–2018, with the International Court of Justice (ICJ) eventually granting rights to Singapore. The ensuing legal battle led to renewed interest in the geography and post-19th century history of the island. The most recent breakthrough, however, provides a glimpse into an even earlier history of Pedra Branca—and by extension, Singapore—as shipwrecked remains dating from the 14th century were uncovered in the surrounding waters. Historical research on the ancient history of Pedra Branca has been mostly neglected by scholars over the years; thus, this paper aims to shed some light on this enigmatic history of the island and at the same time establish its history and significance by utilizing pre-British-colonization historical cartographical data from as early as the 15th century.
