The pronunciation guide uses the ARPABET phonetic system—the same system used in speech recognition and text-to-speech applications.

Vowel Examples:
AE1 = cat, bat
EH1 = bed, head
IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

Certainty is the state of being sure or convinced of truth. It raises questions about knowledge and doubt.

Detailed Definition
Philosophically, certainty has been central to debates about epistemology, particularly in Descartes’ quest for indubitable knowledge. In poetry, it often appears as something questioned or destabilised. Poets explore the tension between certainty and uncertainty, using ambiguity to reflect the limits of knowledge and perception.
Example
Example in poetry:
Descartes's search for certainty — the cogito as the one indubitable foundation after radical doubt — haunts much modern poetry, which either seeks a new ground of certainty or accepts that certainty is unattainable and explores the poetics of uncertainty; Keats's "negative capability" is explicitly defined against the pursuit of certainty — the great poet must resist the "irritable reaching after fact and reason" and remain capable of dwelling in uncertainty, mystery, and doubt; A poet writing in the aftermath of trauma might find that the experience has shattered ordinary certainty — the certainty of the body's safety, of the world's predictability — and the poem becomes an exploration of what remains when certainty is gone; Wittgenstein's "On Certainty" argues that certainty is not a mental state but a practice — we act from certainty rather than knowing it — and this insight informs Language poetry's interrogation of the certainties embedded in grammar and common speech; Emily Dickinson's use of the dash and the slant rhyme produces a formal uncertainty that mirrors the philosophical uncertainty of her theological and metaphysical explorations — certainty is perpetually deferred at the level of sound and syntax; Tennyson's "In Memoriam" dramatizes the loss of religious and metaphysical certainty in the face of grief and geological deep time, and the poem's movement from despair to qualified hope represents not a recovery of certainty but an acceptance of permanent epistemic limitation
Additional Notes
The philosophical quest for certainty reaches its paradigmatic form in Descartes's "Meditations on First Philosophy," where systematic doubt is used to strip away everything uncertain in search of the one indubitable truth: cogito ergo sum. But the search for certainty has been critiqued from multiple directions: Hume showed that causal reasoning cannot achieve strict certainty; Kant showed that certainty about things-in-themselves is impossible; Wittgenstein's "On Certainty" reframed certainty not as a epistemic achievement but as a practical commitment embedded in forms of life. Peirce and the pragmatists argued that absolute certainty is both unattainable and unnecessary — what we need is reliable methods and revisable conclusions. For poets, certainty is both a poetic aspiration (the poem that achieves a definitive statement) and a philosophical problem (what grounds the poem's claim to truth?). Related terms: Cartesian doubt, cogito, infallibility, apodeictic certainty, Wittgenstein, fallibilism.
