An evening pause: This is entertaining, in that it demonstrates the ability of English to absorb an endless number of words, even words that are absolutely ridiculous. Most of these words are unknown because they are hard to say and their meaning can be stated more efficiently and simply using normal vocabulary. I must also add that Tharoor is a Indian politician from the socialist Congress Party, now the minority party in India with the rise the present conservative government under President Modi.
I am therefore not surprised that he is skilled with using big words that can help him obfuscate his meaning, while making him seem erudite.
