Tamil Loanwords in Sinhala - Time of Borrowing

Time of Borrowing

In many cases, the appearance of a loanword in a language indicates whether the borrowing is old or more recent: The more a word deviates from the "original" one, the longer it must have been a part of the respective lexicon, because while being used, a word can undergo changes (sometimes regular sound changes along with the native words). The inversion of this argument is not possible since loanwords already matching the linguistic requirements of the target language may remain unchanged. Thus, the word täpäl (Tamil tapāl) gives away its old age because the respective umlaut processes took place before the 8th century; iḍama (Tamil iṭam) however needn't be a recent borrowing, because no sound changes that could have affected this word have taken place in Sinhala since at least the 13th century.
