Linguistic Shift: From Vedic to Classical Sanskrit's Influence on Prakrits	c. 5th-4th Century BCE	The formalization of Classical Sanskrit by Panini's Astadhyayi around the 5th-4th century BCE, while not an 'amendment' to Pali or Prakrit, significantly influenced the linguistic landscape. It established a high-status, grammatically precise language, against which the 'unrefined' Prakrits were often contrasted. This 'amendment' in linguistic perception and standardization created a diglossic situation where Sanskrit held prestige, but Prakrits thrived as popular and literary vernaculars, shaping their distinct developmental paths.	Reinforced the distinction between the elite Sanskrit and the popular Prakrits, influencing their respective literary domains. It also provided a stable linguistic reference point from which Prakrit deviations could be analyzed by grammarians.
Evolution to Apabhramsha and Emergence of Regional Languages	c. 7th-12th Century CE	The gradual evolution of various Prakrit dialects into Apabhramsha represents a significant 'amendment' in the linguistic trajectory. Apabhramsha, meaning 'corrupted' or 'deviated,' was a late Middle Indo-Aryan stage characterized by further phonetic decay, loss of inflections, and a move towards analytical structures. This was not a single language but a collection of regional dialects that directly transitioned into the early forms of modern Indo-Aryan languages. This shift marks the decline of literary Prakrits as dominant forms.	Led to the fragmentation of the MIA stage and the eventual birth of distinct modern Indo-Aryan languages like Hindi, Bengali, Marathi, and Gujarati, each evolving from a specific regional Apabhramsha. It marked the end of Prakrit's widespread literary dominance.
