Dysgraphia is a condition that results in difficulty writing words. This can be due to issues with fine motor skills, memory, or understanding. Dyslexia is a learning disorder that involves difficulty reading due to problems identifying speech sounds and learning how they relate to letters and words. Anomia is a form of aphasia characterized by difficulty in recalling words or names. Agrammatism is a type of aphasia characterized by difficulty producing functional words, resulting in speech that often lacks grammatical markers or function words.

A dictionary is typically an alphabetical arrangement of words with lexicographic details. A thesaurus, on the other hand, involves the presentation of domain-based conceptual equivalents. A glossary provides explanations of concepts of the terms and words, often in a specific context such as a book or field of study. A wordbook, while similar to a dictionary, often includes a thematic classification of words.

The field of Philology emerged first, focusing on the historical study of languages and literature. Historical Linguistics, a subset of Philology, studies the evolution of languages over time. Next, Behaviourism emerged, a theory that language is a set of habits that can be acquired through repetitive conditioning. Structural Linguistics, focusing on the structures that constitute a language, came next. Finally, Generative Grammar, a theory by Noam Chomsky, appeared, focusing on the innate aspects of language.

The vowel height indicates the vertical position of the tongue during the articulation of a vowel. 'i' is a high front vowel, 'e' is a mid-front vowel, 'ɛ' (represented as 'ae') is a low-mid front vowel, indicating that the tongue is positioned halfway between a mid vowel and an open vowel.

The order 'sound to situation' goes from the smallest unit of language to the largest. Phonology deals with the sound system of languages. Morphology involves the structure of words. Syntax addresses the rules that govern the structure of sentences. Semantics explores the meaning of words, sentences, and texts. Discourse analysis focuses on larger units of language such as conversations or written texts.

In creating a language model in Natural Language Processing, we start with the creation of a gold data set, which serves as a standard for training and evaluating models. Next is training the model on this dataset, followed by testing the model to see how it performs on unseen data. Finally, the model is evaluated based on various metrics to determine its performance.

Lexical context is the set of words and their meanings in a given passage. Syntactic context is the grammatical relationship between words in a sentence. Topical context relates to the topic being discussed. Discourse context is the larger dialogue or discussion within which the sentence is placed. Finally, global context refers to the overall situation or background that surrounds a text or discourse, including cultural, social, and historical aspects.
