निगार a kind of sound which appa- rently is made up of a combina- tion of three phonetic elements ह्, म् and नासिक्य. It is a peculiar sound through both the mouth and the nose, although no specific place of production is assigned to it; cf अविशेषस्थानौ संस्वांदनिगारौ। हकार- मकारनासिक्या वा निगारे R.T.11.

निघण्टु a name given to a collection of words which are mainly Vedic. In ancient times such collections were possibly very general and numerous and the works or trea- tises on derivation such as the Nirukta of Yaska were based upon them; cf. निघण्टवः कस्मात् । निगमा इमे भवन्ति । छन्दोभ्यः समाहृत्य समाहृत्य समाम्नातास्ते निगन्तव एव सन्तो निगमनान्निघण्टव उच्यन्ते इत्यौपमन्यवः । अपि वा आहननादेव स्युः | समाहता भवन्ति । यद्वा समाहृता भवन्ति (Nir.I.1) where the word is deri- ved from गम्,or हन् or हृ. The word निघण्टु is taken as synonymous with निगम by Durgacarya.

निघात toning down; the grave accent; the root निहन् in its various forms is used in the sense of toning down the voice and the word निघात is used in the sense of the grave accent (अनुदात्तस्वर) in the Vyakarana and Pratisakhya works; cf. also the words शेषनिघात, सर्वनिघात, etc.; cf. समानवाक्ये निघातयुष्मदस्मदादेशाः P.

नित् an affix possessed of the mute indicatory letter न्, the word cha- racterized by which has the acute accent on the vowel of the first syllable; e. g. गार्ग्यः, वात्स्यः, cf Kas. on P.VI.1.197.

नित्य (1) eternal, as applied to word or Sabda in contrast with sound or dhvani which is evanescent (कार्य ). The sound with meaning or without meaning,made by men and animals is impermanent; but the sense or idea awakened in the mind by the evanescent audible words on reaching the mind is of a per- manent or eternal nature; cf. स्फोटः शब्दो ध्वनिस्तस्य व्यायामादुपजायते; cf. also व्याप्तिमत्त्वा्त्तु शब्दस्य Nir.I.1 ; (2) cons- tant; not liable to be set aside by another; cf. उपबन्धस्तु देशाय नित्यम्, न रुन्धे नित्यम्। नित्यशब्दः प्राप्त्यन्तरानिषेधार्थः T.Pr.I.59, IV.14; (3) original as constrasted with one introduced anew such as an augment; cf. T. Pr. VI.14; (4) permanently func- tioning, as opposed to tentatively doing so; cf. नित्यविरते द्विमात्रम् R. T.37; (5) unchangeable, perma- nent, imperishable; cf. अयं नित्यशब्दो- स्त्येव कूटस्थेष्वविचालिषु भावेषु वर्तते M.Bh. on P. VIII. 1.4; (6) always or invariably applying, as opposed to optional; the word in this sense is used in connection with rules or operations that do not optionally apply; cf. उपपदसमासो नित्यसमासः, षष्ठीसमासः पुनार्वेभाषा; M. Bh. on P.II.2.19; (7) constant,as appli- ed to a rule which applies if another simultaneously applying rule were to have taken effect, as well as when that other rule does not take effect; cf. क्वचित्कृताकृतप्रसङ्गमा- त्रेणापि नित्यता Par. Sek. Pari 46. The operations which are nitya according to this Paribhasa take
