Empiricism in linguistics (often associated with Structuralism and Behaviorism, like B.F. Skinner or Leonard Bloomfield) dictates that language must be studied through directly observable sense data (Option 2)—actual spoken and recorded utterances.

(Note: Exploring "innate language knowledge" or the unseen "human mind" is the hallmark of Noam Chomsky's Rationalist/Generative approach, which aggressively rejected empiricism).

Noam Chomsky famously founded Transformational-Generative Grammar (TGG). He borrowed both these concepts directly from formal mathematics and computer science logic.

• (D) Generation: In math, a set of rules can "generate" infinite sequences of numbers. Chomsky argued that human grammar uses a finite set of rules to "generate" an infinite number of possible valid sentences.
• (C) Transformation: Taking a deep, underlying mathematical/syntactic structure and applying a rule to "transform" it into a new surface structure (e.g., transforming an active sentence into a passive sentence).

The English word "potato" was borrowed in the 1560s from the Spanish word patata.

The Spanish themselves had combined two indigenous languages from the Americas to create the word: the Taino word batata (meaning sweet potato) and the Quechua word papa (meaning white potato). English explorers adopted the Spanish version when the vegetable was brought over to Europe.

A Phonestheme is a specific cluster of sounds (phonemes) that consistently carries a specific semantic meaning or association across many different words.

For example, the sound cluster "gl-" in English is strongly associated with light and shining: glow, gleam, glisten, glitter, glint, glare, gloss. Another example is "sn-" associated with the nose: snort, sniff, snot, sneeze, snore.

(Note: A 'phoneme' is the smallest unit of sound that changes meaning (pat vs bat), but the letter 'p' itself has no inherent meaning).

In sociolinguistics, when stable bilinguals use two different languages for distinct, separate social contexts, the languages are performing a complementary function (they complement each other rather than competing).

In India, a person might use their mother tongue (e.g., Tamil or Marathi) exclusively for home, family, and cultural events, but seamlessly switch to English as a "link language" to complement their life by using it exclusively for higher education, high-level business, or inter-state administrative communication.

In Noam Chomsky's famous linguistic dichotomy (Competence vs. Performance), Performance refers to the actual, messy, real-world use of language.

• (B) True: It is the specific utterance produced by a speaker in real-time. (This makes it analogous to Saussure's concept of parole, not langue).
• (D) True: Because human brains have memory limits, distractions, and psychological stress, actual "Performance" is full of stutters, false starts, "ums," and grammatical errors.

(Note: A and C perfectly describe Chomsky's concept of "Competence").

Statement I is True: Modern linguistics is a descriptive science. Unlike traditional "Grammar Police," linguists do not passionately judge language as "good" or "bad"; they dispassionately observe and describe how language actually functions, much like a biologist observes a cell.

Statement II is False: A "polyglot" is someone who speaks many languages. While helpful, it is absolutely not a requirement to be a linguist. Many brilliant linguists only speak one or two languages but possess a deep theoretical understanding of syntax and phonology.

The neurological process of hearing and then repeating a spoken word (the Wernicke-Geschwind model) follows a strict biological sequence:

1. (D) Posterior Speech Cortex (Wernicke's Area): First, the sound is received here to be decoded and understood.
2. (A) Arcuate Fasciculus: The understood signal travels across this bundle of nerve fibers.
3. (B) Anterior Speech Cortex (Broca's Area): The signal arrives here, where the brain organizes the grammatical structure and plans how to speak the word.
4. (C) Motor Cortex: Finally, Broca's area sends the command to the Motor Cortex, which physically moves the tongue, lips, and vocal cords to produce the sound.

In phonology, Syncope is the linguistic term for the deletion of a vowel (or sometimes a consonant) from the middle of a word.

This is extremely common in casual English speech to increase speed and efficiency. For example, the word "family" is usually pronounced fam-lee (deleting the middle 'i'). Other examples include ev-ry (every) and choc-late (chocolate).

(Note: Aphaeresis is the loss of a sound at the BEGINNING of a word, like saying "possum" instead of "opossum" or 'bout' instead of 'about').

The Survey of English Usage (SEU) was founded in 1959 by the eminent British linguist Randolph Quirk at University College London (UCL).

It was a massive, pioneering project in corpus linguistics. Quirk and his team collected one million words of real, naturally occurring spoken and written British English (ranging from legal texts to dinner-table conversations) on index cards. This data formed the empirical basis for his monumental work, A Comprehensive Grammar of the English Language (1985).
