LABELING
(Syntax) Among the fundamental questions in minimalist research is why human language has φ-feature agreement and Case. Chomsky (2013) proposes a partial answer for this with his labeling algorithm. The operation Merge, which combines two elements α and β into {α, β}, is minimally required for language. This operation, he argues, must accompany an algorithm that specifies the nature of the formed object. For example, when a verbal element and a nominal element form a constituent, information must be provided whether the constituent is verbal (VP) or nominal (NP). His proposal is that φ-feature agreement plays a crucial role in this labeling process. On the other hand, it is proposed in Chomsky (2008), for example, that Case is necessary for φ-feature agreement and is valued through it. This leads to the picture in (1), where '→' means 'requires':

1. Merge → Labeling → φ-feature agreement → Case

LABELING ALGORITHM
(Syntax) Merge is defined as producing a simple set (i.e. Merge (α, β) = {α, β}), which we may call a syntactic object (SO). The rise of Merge over X'-schemata recaptures the aspect of discrete infinity in phrase structure as recursive application of Merge (i.e. Merge (γ, {α, β}) = {γ, {α, β}}), a property specific to human beings (cf. Fujita 2009). Merge does not entail the application of projection; rather, it purely ensures set formation, hence the labeling algorithm (LA) (Chomsky 2013):

The labeling algorithm (LA)
Suppose SO = {H, XP}, H a head and XP not a head. Then LA will select H as the label, and the usual procedures of interpretation at the interfaces can proceed.

LABOV'S ATTENTION-TO-SPEECH MODEL
(Sociolinguistics) Labov's "attention to speech" model (1972) holds that speakers shift styles in reaction to the formality of the speech situation.
   Stylistic variation is conditioned by how much attention speakers pay to their own speech as they converse. Speech registers, under this model, fall along a continuum according to self-consciousness of speech; less self-conscious varieties are labeled "casual" or "informal," and registers characterized by more self-consciousness are termed "careful" or "formal." Less self-conscious registers are also held to be further removed from standard or prestige language varieties than more self-conscious speech, which tends toward what the speaker perceives to be more standard speech. | Schilling-Estes, 1998

LABOV'S VERNACULAR PRINCIPLE
(Sociolinguistics) Labov's Vernacular Principle holds that the style which is most regular in its structure and its relation to the evolution of the language is the vernacular, in which the minimum attention is paid to speech. (1972) The Vernacular Principle has led sociolinguists to focus on speech which they determine to be non-self-conscious, at the expense of stylistic varieties such as performance speech, which are identified as self-conscious. | Schilling-Estes, 1998

LAMBDA (λ)

1. (Semantics) A notion developed in mathematical logic and used as part of the conceptual apparatus underlying formal semantics. The lambda operator is a device which constructs expressions denoting functions out of other expressions (e.g. those denoting truth values) in a process called lambda abstraction. The process of relating equivalent lambda expressions is known as lambda conversion. Several kinds of lambda calculus have been devised as part of a general theory of functions and logic, functions here being defined as sets of unordered pairs (graphs). The approach has proved attractive to linguists because of its ability to offer a powerful system for formalizing exact meanings and semantic relationships, and lambda notions have helped to inform a number of linguistic theories, notably Montague grammar and categorial grammar. | David Crystal, 2008
2. (Acoustics) The symbol for wavelength.

LAMBDA CALCULUS
(Mathematical Logic, Semantics) A formal system for expressing computation based on function abstraction and application using variable binding and substitution. It is a universal model of computation that can be used to simulate any Turing machine. It was introduced by the mathematician Alonzo Church in the 1930s as part of his research into the foundations of mathematics.
 Lambda calculus consists of constructing lambda terms and performing reduction operations on them. In the simplest form of lambda calculus, terms are built using only the following rules:

Syntax	Name	Description
x	Variable	A character or string representing a parameter or mathematical/logical value.
(λx.M)	Abstraction	Function definition (M is a lambda term). The variable x becomes bound in the expression.
(M N)	Application	Applying a function to an argument. M and N are lambda terms.

Operation	Name	Description
(λx.M[x]) → (λy.M[y])	α-conversion	Renaming the bound variables in the expression. Used to avoid name collisions.
((λx.M) E) → (M[x := E])	β-reduction	Replacing the bound variables with the argument expression in the body of the abstraction.

LAMINAL
(Phonetics) An articulation involving the blade of the tongue (= lamina). | Utrecht Lexicon of Linguistics, 2001

LANGUAGE SHIFT
(Diachronic) Or, language transfer, or, language replacement, or, language assimilation. The process whereby a speech community shifts to a different language, usually over an extended period of time. Often, languages that are perceived to be higher status stabilize or spread at the expense of other languages that are perceived by their own speakers to be lower-status. An example is the shift from Gaulish to Latin during the time of the Roman Empire. | Wikipedia, 2022

LARYNGEAL FEATURES
(Phonetics) One proposal:

• Sources:
  • gl = glottal.
  • epl = epilaryngeal.
  • nil = no phonation.
• Larynx height (LH):
  • N = neutral larynx.
  • L = lowered larynx.
  • R = raised larynx.
• [±cet] = constricted epilaryngeal tube.
• [±sg] = spread glottis.
• [±stf] = stiff vocal folds.

LARYNGEAL NEUTRALIZATION
(Phonology) The most common phonological process involving laryngeal features is laryngeal neutralization, wherein all laryngeal distinctions are lost in syllable-final position. | Linda Lombardi, 1995

LATE-PEAK ACCENT

1. (Prosody) In early-peak or late-peak accents, f0 peaks either precede or follow the stressed syllable they are associated with. | Katharina Zahner, Sophie Kutscheid, and Bettina Braun, 2019
2. (Prosody) Previous research has demonstrated that nuclear intonation contours in German crucially differ with respect to f0-peak alignment (Kohler 1991, Grice et al. 2005, Niebuhr 2022). The f0 peak may either precede the stressed syllable (H+L*, early-peak accent), or follow it (L*+H, late-peak accent), or be aligned within the stressed syllable (L+H*, medial-peak accent). | Katharina Zahner-Ritter, Marieke Einfeldt, Daniela Wochner, Angela James, Nicole Dehé, and Bettina Braun, 2022

LEFT BRANCH CONDITION
(Syntax) Ross (1967, 1986) proposed the Left Branch Condition (LBC), which blocks movement of the leftmost constituent of an NP. The condition has been used in the literature to block extraction of determiners, possessors, and adjectives out of NP.

1. * Whose_i did you see [ t_i father ]?
2. * Which_i did you buy [ t_i car ]?
3. * That_i he saw [ t_i car ].
4. * Beautiful_i he saw [ t_i houses ].
5. * How much_i did she earn [ t_i money ]?

LEFT-BRANCH EXTRACTION

LEFT DISLOCATION

1. (Syntax) The construction of e.g. (1):
   1. This next man, have I got to see him?
    Distinguished from simple fronting (2) by a pronoun (him) or other anaphoric element in the normal position of the dislocated element.
   2. This next man have I got to see?
    | Concise Oxford Dictionary of Linguistics, 2007
2. (Syntax) The sentence My mother, she is a good person is an example of a construction where a non-vocative noun phrase in initial position is set off from a following sentence that contains one or more pronouns coreferential with the initial NP. Since Haj Ross's 1967 dissertation Constraints on Variables in Syntax, this construction has been known as left dislocation. Haj's examples included:
   1. The man my father works with in Boston, he's going to tell the police that the traffic expert has set that traffic light on the corner of Murk Street far too low.
   2. My father, he's Armenian, and my mother, she's Greek.
   3. My wife, somebody stole her handbag last night.
   When the pronoun is sentence-initial, you might think that it's in apposition with the left-dislocated noun phrase. But this generally makes neither semantic nor prosodic sense. If the structure were really

   My father – he – 's Armenian.

   the phrasing would be different (and strange), and it's hard to see why one would want to add the pronoun, which would add none of the parallel information that appositives usually do.
    The third example (My wife, somebody stole her handbag last night) illustrates the fact that the pronoun need not be adjacent to the left-dislocated noun at all. (Though examples with the pronoun in subject position are by far the commonest.)
    Constructions of this general type are common across the languages of the world, and in so-called topic-prominent languages, they're the norm. The left-dislocation structure is often said to divide the sentence into topic and comment, or some similar sort of articulation of information. (This works when the initial item is a full noun phrase, referenced in the following sentence by a pronoun or pronouns, but it wouldn't work the other way around. There's a lot more to be said about the pragmatics of LD, and there's a large literature discussing it. | Mark Liberman, 2008

LEFT PART STRANDING
(Grammar) A novel ellipsis phenomenon that deletes the second part of compounds, stranding the left side of the compound in sentence-final position:

1. Deze
   this

   lift
   lift

   is
   is

   zevenpersoons,
   seven.person.ADJ

   en
   and

   die
   that

   acht
   eight

   ___ (Dutch)
    

   'This lift can carry seven people, and that one can carry eight people.'

1. It is only possible under clausal but not phrasal coordination.
2. It preferably occurs in compounds that are the adjectival predicate of a clause.
3. It preferably co-occurs with gapping or TP-ellipsis (fragments, sluicing).
4. The stranded part is necessarily contrastive.

LEVELING
(Sociolinguistics) The eradication of marked or minority forms in situations of dialect competition, where the number of variants in the output is dramatically reduced from the number in the input. | David Britain, 2001

LEVELING, MORPHOLOGICAL
(Morphology) Or, paradigm leveling. The generalization of an inflection across a linguistic paradigm, a group of forms with the same stem in which each form corresponds in usage to different syntactic environments (SIL 2015), or between words (Singh 2005). The result of such leveling is a paradigm that is less varied, having fewer forms (Hazen, 2014).
 When a language becomes less synthetic, it is often a matter of morphological leveling. An example is the conjugation of English verbs, which has become almost unchanging today, thus contrasting sharply, for example, with Latin, in which one verb has dozens of forms, each one expressing a different tense, aspect, mood, voice, person, and number. For instance, English sing has only two forms in the present tense (I/you/we/they sing and he/she sings), but its Latin equivalent cantāre has six: one for each combination of person and number. | Wikipedia, 2022
