Value that a sequence or function approaches as its input approaches a given point or grows without bound; the foundation on which continuity, derivatives and integrals are formally defined.
- Intégrale
- Related: Dérivée, Primitive
Accumulated total of a function over an interval, interpreted as signed area under its curve; computed exactly using antiderivatives via the fundamental theorem of calculus.
- Primitive
- Related: Intégrale, Dérivée
A function whose derivative equals a given function; every continuous function has infinitely many primitives differing by an additive constant, used to evaluate definite integrals.

Sequence in which each term is obtained by adding a fixed constant to the previous one; its general term is linear in the index and its partial sums grow quadratically.
- Suite géométrique
- Related: Suite arithmétique, Limite
Sequence in which each term equals the previous term multiplied by a fixed ratio; its behaviour depends on whether that ratio has absolute value below, equal to, or above one.

Weighted average value of a random variable, each outcome weighted by its probability; it describes the long-run mean of repeated independent trials of the same experiment.

Property of two events where the occurrence of one does not change the probability of the other, equivalently their joint probability equals the product of their individual probabilities.
- Continuité
- Related: Limite, Théorème des valeurs intermédiaires
Property of a function whose value at each point equals its limit there, so its graph has no breaks; on a closed interval it guarantees bounds and intermediate values.

Result stating that a continuous function on a closed interval attains every value between its endpoint values; used to prove existence of solutions to equations.

- Related: Matrice, Système linéaire
Scalar assigned to a square matrix that indicates whether the matrix is invertible and measures how the associated linear transformation scales areas or volumes.
- Système linéaire
- Related: Matrice, Déterminant
Collection of linear equations in several unknowns solved simultaneously; its solution set is described using matrix row reduction and depends on rank and consistency conditions.
- Figure de style
- Related: Métaphore, Champ lexical
Deliberate deviation from ordinary expression used for expressive effect, such as comparison, metaphor, hyperbole or anaphora; identified and interpreted in literary commentary and text analysis.
- Métaphore
- Related: Figure de style, Champ lexical
Figure of speech that transfers meaning by asserting an implicit resemblance between two things without a comparative word, unlike a simile which uses an explicit comparison marker.
- Champ lexical
- Related: Figure de style, Registre de langue
Set of words in a text sharing a common semantic theme, such as terms of seafaring or of grief; its identification supports interpretation of tone and subject matter.
- Registre de langue
- Related: Champ lexical, Narrateur
Level of language used in a text or utterance, such as formal, standard or familiar, determined by vocabulary, syntax and social context; it shapes tone and characterization.
- Narrateur
- Related: Focalisation, Registre de langue
Voice that tells a narrative, distinct from the author; its position, knowledge and reliability determine focalization and how the reader receives the story's events.
- Focalisation
- Related: Narrateur, Figure de style
Perspective from which a narrative is presented, ranging from omniscient narration to restricted or external viewpoint; it controls what information the reader can access.
- Thèse
- Related: Argument, Sophisme
Central claim that a philosophical or argumentative text defends, supported by premises and reasoning; identifying it is the first step in analysing an argument.
- Argument
- Related: Thèse, Sophisme
Set of premises offered as reasons supporting a conclusion; assessed for validity, meaning the conclusion follows from the premises, and for soundness of those premises.
- Sophisme
- Related: Argument, Thèse
Reasoning that appears persuasive but is logically flawed, such as attacking a person instead of the claim or begging the question; recognized and named in critical analysis.

Philosophical position holding that knowledge derives from sensory experience rather than innate ideas; associated with thinkers who treat the mind as receiving impressions from observation.
