UGC-NET (NTA) LINGUISTICS, JUNE-2025

Human language is considered a unique cognitive system that no other species possesses in its full complexity. It involves advanced symbolic thinking, creativity, recursion, and the ability to generate an infinite number of sentences. These features reflect the "human essence," meaning that only human beings-among all known living forms-display such sophisticated linguistic capacity. This includes the ability to learn grammar naturally, understand abstract concepts, and use language for cultural transmission.

The connection between the sound of a word and the meaning it carries is generally arbitrary. There is no natural, logical, or physical reason why the sound sequence /tree/ should refer to the concept of a "tree." Different languages use completely different sounds for the same object, proving arbitrariness. For example, English "dog," Hindi "कुत्ता, " French "chien, " and Japanese “t (inu)” show that sound-meaning connections are based on convention, not natural resemblance.

Linguists try to identify features that exist across all human languages. These shared
characteristics-such as the presence of nouns and verbs, hierarchical structure, and rules for word formation-are called linguistic universals. This field seeks to understand the underlying principles common to every human language, irrespective of geographical or cultural differences. Such universals support the idea that the human brain has an innate language faculty, sometimes referred to as Universal Grammar (UG).

Displacement refers to the ability of humans to talk about things beyond the immediate here and now-events in the past, future, or imaginary worlds. For example, a person can describe what happened yesterday, make plans for tomorrow, or talk about places they have never visited. No animal communication system (such as bee dances or bird calls) shows full displacement with the same flexibility and unlimited range as human language. This feature highlights the abstract and symbolic nature of human communication.

The difference between vowel phonemes /i/ and /u/ lies primarily in lip rounding. The vowel /i/ (as in "see") is produced with unrounded lips, while /u/ (as in "too") requires rounded lips. Both vowels are high vowels, but differ in tongue position as well-/i/ is a high front vowel, and /u/ is a high back vowel. However, the only. correct distinction among the options given is that /i/ is unrounded and /u/ is rounded, which is a fundamental articulatory feature used in phonetics.

Panini's Siva-sutras organize Sanskrit sounds into phonological classes using pratyaharas. The pratyahara ac is formed from the first sound a up to the marker c, and this range includes all vowels of Sanskrit: a, ā, i, ī, u, ū, r, ī, 1, e, ai, o, au. Panini uses ac to collectively refer to the full vowel inventory, which is crucial in rules of sandhi and morphological operations in Sanskrit grammar.

The concept of archiphoneme-a higher-level phonological unit representing the neutralized features of two phonemes-was developed by the Prague School linguist Nikolai Trubetskoy. He introduced it to describe situations where phonemic contrast disappears in certain environments. For example, in final position in German, /t/ and /d/ neutralize, leading to an archiphoneme {T}. Trubetskoy's work laid the foundation for structural phonology in the 20th century.

The Theory of Lexical Phonology (1986) is authored by K.P. Mohanan, a major contributor to the development of Lexical Phonology and Morphology. The book integrates phonological rules with morphological structure and proposes that some phonological operations apply in the lexicon while others apply post-lexically. This model helped linguists understand rule ordering, strata, and the interactions between morphology and phonology.

The process where a word shifts grammatical category without any change in form is called conversion. In the examples:
• a hoover (noun) → to hoover (verb)
• a service (noun) → to service (verb)
The phonological shape remains identical; only the syntactic function changes. Conversion is common in English, such as to bottle, to hammer, to email, and illustrates the flexibility of derivational morphology without overt affixation.

The distinction between Item and Arrangement (IA) and Item and Process (IP) models was proposed by Charles F. Hockett.
• In IA, words are seen as arrangements of morphemes, like building blocks combined
linearly.
• In IP, morphological processes (e.g., affixation, internal change, reduplication)
operate on underlying forms to derive new forms.
Hockett's framework helped classify different computational views of morphology and remains a foundational distinction in linguistic theory.
