The Sanskrit grammatical tradition, Vyakarana, one of the six Vedangas, began in the late Vedic period and culminated in the Astadhyayi of Panini, which consists of 3990 sutras (ca. fifth century BCE). About a century after Panini (around 400 BCE), Katyayana composed Vartikas on the Panini sutras. Patanjali, who lived three centuries after Panini, wrote the Mahabhasya, the "Great Commentary" on the Astadhyayi and Vartikas. Because of these three ancient Vyakaranins (grammarians), this grammar is called Trimuni Vyakarana. To understand the meaning of the sutras, Jayaditya and Vamana wrote a commentary, the Kasika, in 600 CE. Paninian grammar is based on 14 Shiva sutras (aphorisms), where the whole matrika (alphabet) is abbreviated. This abbreviation is called the Pratyahara.

At the time of her accession, the government was led by the Whig prime minister Lord Melbourne, who at once became a powerful influence on the politically inexperienced Queen, who relied on him for advice. Charles Greville supposed that the widowed and childless Melbourne was "passionately fond of her as he might be of his daughter if he had one", and Victoria probably saw him as a father figure. Her coronation took place on 28 June 1838 at Westminster Abbey. Over 400,000 visitors came to London for the celebrations. She became the first sovereign to take up residence at Buckingham Palace and inherited the revenues of the duchies of Lancaster and Cornwall as well as being granted a civil list allowance of 385,000 per year. Financially prudent, she paid off her father's debts.

Ah, so.. Charles Greville
