Early Konkani was marked by the use of pronouns like dzo, jī, and jẽ. These are replaced in contemporary Konkani by koṇa. The conjunctions yedō and tedō ("when" and "then") which were used in early Konkani are no longer in use. The use of -viyalẽ has been replaced by -aylẽ. The pronoun moho, which is similar to the Brajbhasha word mōhē has been replaced by mākā. Medieval This era was marked by several invasions of Goa and subsequent exodus of some Konkani families to Canara (today's coastal Karnataka), and Cochin. Exodus (between 1312–1327) when General Malik Kafur of the Delhi Sultans, Alauddin Khalji, and Muhammed bin Tughlaq destroyed Govepuri and the Kadambas Exodus subsequent to 1470 when the Bahamani kingdom captured Goa, and subsequent capture in 1492 by Sultan Yusuf Adil Shah of Bijapur Exodus of converted Muslims to Bijapur-held territory due to the Portuguese conquest of Goa in 1510 Migration of Hindu converts to Canara in South India after the Christianisation of Goa, the subsequent Goa Inquisition, and the Sackings of Goa and Bombay-Bassein. These events caused the Konkani language to develop into multiple dialects with multiple scripts. The exodus to coastal Karnataka and Kerala required Konkani speakers in these regions to learn the local languages. This caused penetration of local words into the dialects of Konkani spoken by these speakers. Examples include dār (door) giving way to the word bāgil. Also, the phoneme "a" in the Salcette dialect was replaced by the phoneme "o". Other Konkani communities came into being with their own dialects of Konkani. The Konkani Muslim communities of Ratnagiri and Bhatkal came about due to a mixture of intermarriages of Arab seafarers and locals as well as conversions of Hindus to Islam. Another migrant community that picked up Konkani are the Siddis, who are descended from Bantu peoples from South East Africa that were brought to the Indian subcontinent as slaves. Contemporary Contemporary Konkani is written in Devanagari, Kannada, Malayalam, Persian, and Roman scripts. It is written by speakers in their native dialects. The Goan Antruz dialect in the Devanagari script has been promulgated as Standard Konkani. Revival Konkani language was in decline, due to the use of Portuguese as the official and social language among the Christians, the predominance of Marathi over Konkani among Hindus, and the Konkani Christian-Hindu divide.
