Definition
Meaning
A change in the form of a word (typically the ending) to express a grammatical function such as tense, mood, person, number, case, or gender.

Linguistics
Semantic Notes
In linguistics, 'inflection' is distinct from 'derivation'. Inflection creates different forms of the same word (e.g., walk, walks, walked, walking), while derivation creates new words (e.g., walk → walker). The extended meaning relating to voice is common in performance contexts.

Conceptual Metaphor
GRAMMAR IS SHAPE (words are bent/modified). COMMUNICATION IS A JOURNEY (voice inflection is a rise and fall on the path of speech).

- The mathematical 'point of inflection' is 'tochka peregiba' (точка перегиба).
Common Mistakes
- Misspelling as 'inflexion' (archaic).
- Confusing 'infection' with 'inflection'.
- Using it as a synonym for 'accent' (regional pronunciation) rather than grammatical change or pitch variation.

FAQ
Frequently Asked Questions
No. Conjugation is a subtype of inflection that applies specifically to verbs. Inflection is the broader term for all grammatical changes to words (verbs, nouns, adjectives, etc.).
In linguistics, 'inflection' primarily refers to word form changes. 'Intonation' refers specifically to the rise and fall of pitch in speech. However, in general usage, 'inflection' is often used synonymously with 'intonation' when talking about voice.
Yes. In calculus, a 'point of inflection' (or 'inflection point') is a point on a curve where the curvature changes sign, i.e., from concave up to concave down, or vice versa.
Compared to languages like Latin, Russian, or Arabic, English has lost most of its case endings on nouns and adjectives. It relies more on word order and prepositions than on inflectional changes to show grammatical relationships.
