Konkani alphabets refers to the five different scripts (Devanagari, Roman, Kannada, Malayalam and Perso-Arabic scripts) currently used to write the Konkani language.
As of 1987, the "Goan Antruz dialect" in the Devanagari script has been declared Standard Konkani and promulgated as an official language in the Indian state of Goa. As Konkani in the Roman script is not mandated as an official script by law. However, an ordinance passed by the government of Goa allows the use of Roman script for official communication. This ordinance has been put into effect by various ministries in varying degrees. For example, the Goa Panchayat Rules, 1996 stipulate that the various forms used in the election process must be in both the Roman and Devanagari script.
The earliest inscription in Konkani in Goykanadi script (extinct now) is of the Gupta period in the 2nd century CE found at Aravalem, Goa. It reads
(On the top of Shachipura)
The famous inscription at the foot of the colossal Jain monolith Gomaṭēśvara (Bāhubali) Konkani: gomṭo - pretty masc., īśvar - God at Shravanabelagola of 981 CE reads,
(Chavundaraya got it done, Gangaraya got it done again.)
The rules for writing Konkani in the Devanagari script are elucidated in a book released by the Goa Konkani Academy titled kōṅkaṇī śuddhalēkhanācē nēm. While the rules for writing Konkani in the Roman script are elucidated in a book titled thomas sṭīvans koṅkaṇi kēndr Romi Lipi by writer Pratap Naik, released by Konkani singer Ullās Buyā̃v at Dalgado Konkani Academy.
In Konkani, the anusvāra ं ṃ is traditionally defined as representing a nasal stop homorganic to a following plosive,(anunāsika) and also vowel nasalisation. The precise phonetic value of the phoneme is dependent on the phonological environment. Word-finally, it is realized as nasalization of the preceding vowel (e.g. bā̃yi [bãːyi], "a well"). It results in vowel nasalization also medially between a short vowel and a non-obstruent (tũvẽ [tʊ̃ʋe] "you (acc.)". It is pronounced as a homorganic nasal, with the preceding vowel becoming nasalized allophonically, in the following cases: between a long vowel and a voiced stop (tāṃbo [taːmbo] "copper", cāṃdī [tʃaːndiː] "silver"), between a long vowel and a voiceless stop (dāṃt [daːnt] "tooth"), and also between a short vowel and an obstruent (sāṃbayi- [saːmbay] "to support", The last rule has two sets of exceptions where the anusvāra effects only a nasalization of the preceding short vowel. Words from the first set are morphologically derived from words with a long nasalized vowel (mā̃s [mãs], "meat". In such cases the vowel is sometimes denasalized ([maːs]. The second set is composed of a few words like (pā̃vcẽ [pãʋtʃɛ̃], "to arrive".)
