In the chandas (Vedas) also, the aṅga (stems) 1. asthi 2. dadhi 3. sakthi and 4. akṣi are found to take the substitute an (anaṅ) before the endings other than those mentioned above.,
Thus the substitute is ordained before endings beginning with a vowel. In the Veda it comes before affixes beginning with a consonant. As इन्द्रो दधीचो अस्थ꣡भिः, भद्रं पश्येमाक्ष꣡भिः ॥ The substitute is ordained to come after the Instrumental &c. In the Vedic literature it is found in the Accusative &c. As अस्थानि in अस्थान्युत्कृत्य जुहोति ॥ The substitute comes before case-endings (vibhakti), in the Vedic literature it comes before affixes which are not case-endings, as अक्षण्व꣡ता लाङ्गलेन, अस्थन्व꣡न्तं यदनस्था बिभर्त्ति ॥ See (VI. I. 176).,
