Tamil loanwords in Ancient Greek came about due to the interactions of Mediterranean and South Indian merchants.
Tamil loanwords entered the Greek language throughout different periods in history.
Although there is general consensus that there are Tamil loanwords in Ancient Greek, few of the words have competing etymologies as well.
Tamil mainly entered the lexicon of Classical Malay (and by extension, its modern Malaysian and Indonesian standard variants) with the immigration of South Indian traders and labourers who settled around the Strait of Malacca.
Close contact through commercial networks between India and Maritime Southeast Asia for more than two millennia, bolstered by the establishment of Tamil as a literary language in India starting from the 9th century, allowed the spread of Dravidian loanwords in several local languages of Southeast Asia, including Old Malay and Tagalog.
