Aurally

At the pizzeria in the afternoon of the 31st of January of 2022, I heard the muscular bearded owner speaking in his cellphone, whilst he was eating pizza. He was speaking in Tamil. I told him that I like the way the cursive writing looks. He said that the truth was that he was born and raised in Canada and he could not read or write Tamil. I said that it was good that his parents from Sri Lanka were culturally motivated to pass on Tamil to the next generation, at least, orally and aurally. His family is Hindu.

While differentiation is often not challenging for certain languages (anyone can recognise the difference between Russian and French, or Mandarin and Spanish), as languages become closer the difficulty of aurally separating them increases.
