Form vs Function

04/20/2314

Conflict lexical information is adjective syntactic feature is like a noun

When a word is lexically an adjective but behaves like a noun on syntactic level then it is called as nominal. The ability to take grammatical case marking.

Common Feature of Indian LanguagesAdjectives are declined according to gender and number of

a noun to which they modify in Sanskrit. श्वे�र्ता� धा�विर्ता।

Nominals should not be a part of WN which is semantic net.

Nouns behave as an adjective on syntactic level is an adjectival.

Synsets of adjectivals difficult to cover in Sanskrit

Literal translation ‘मह्यं� विहन्दUलिचत्रपूटाः�� रः�चन्र्ता�।’ किंह8दU विIल्मX – A compound in Sanskrit.It is dissolved in Sanskrit as विहन्दU(भा�षः�यो�म$) लिचत्रपूटाः�.It is संप्र्ताम( र्तात्पू�रुषः.It is not an adjective in Sanskrit Compound.

04/20/2316

When a word is an adjective or a noun lexically but functions as an adverb syntactically then it is called as adverbial.ज�नज�र्ता$�ग�न

All these are nouns lexically.When appear in instrumental or ablative

case acts as an adverbShould they form a part of a synset of an

adverb?

Conclusion

Impact of structural differences of Hindi and

Sanskrit on development of SWN

Lexicalization of derived words needs to be

studied

Historical development of a word should be

considered while developing SWN

Nominals, Adjectivals and Adverbials will not

be considered in SWN
