Jamison. It can fall anywhere in the word and its position often conveys morphological and syntactic information. The presence of an accent system in Vedic Sanskrit is evidenced from the markings in the Vedic texts. This is important because of Sanskrit's connection to the PIE languages and comparative Indo-European linguistics. Sanskrit, like most early Indo-European languages, lost the so-called "laryngeal consonants (cover-symbol *H) present in the Proto-Indo-European", states Jamison. This significantly impacted the evolutionary path of the Sanskrit phonology and morphology, particularly in the variant forms of roots. Pronunciation Because Sanskrit is not anyone's native language, it does not have a fixed pronunciation. People tend to pronounce it as they do their native language. The articles on Hindustani, Marathi, Nepali, Oriya and Bengali phonology will give some indication of the variation that is encountered. When Sanskrit was a spoken language, its pronunciation varied regionally and also over time. Nonetheless, Panini described the sound system of Sanskrit well enough that people have a fairly good idea of what he intended. Morphology The basis of Sanskrit morphology is the root, states Jamison, "a morpheme bearing lexical meaning". The verbal and nominal stems of Sanskrit words are derived from this root through the phonological vowel-gradation processes, the addition of affixes, verbal and nominal stems. It then adds an ending to establish the grammatical and syntactic identity of the stem. According to Jamison, the "three major formal elements of the morphology are (i) root, (ii) affix, and (iii) ending; and they are roughly responsible for (i) lexical meaning, (ii) derivation, and (iii) inflection respectively". A Sanskrit word has the following canonical structure: Root + Affix + Ending The root structure has certain phonological constraints. Two of the most important constraints of a "root" is that it does not end in a short "a" (अ) and that it is monosyllabic. In contrast, the affixes and endings commonly do. The affixes in Sanskrit are almost always suffixes, with exceptions such as the augment "a-" added as prefix to past tense verb forms and the "-na/n-" infix in single verbal present class, states Jamison. Sanskrit verbs have the following canonical structure: Root + Suffix + Suffix + Ending According to Ruppel, verbs in Sanskrit express the same information as other Indo-European languages such as English. Sanskrit verbs describe an action or occurrence or state, its embedded morphology informs as to "who is doing it" (person or persons),
