Lexical inflection, also known by terms like accidence or flection, refers to the process in linguistics where the form of a word is changed to mark various grammatical distinctions. This change typically involves the addition of endings, especially in English, and applies to content words such as nouns, verbs, adjectives, and adverbs. The primary purpose of lexical inflection is to convey grammatical information without altering the word's fundamental meaning or its part of speech.
Understanding the Core Concept
Inflection is a core concept within morphology, the study of word structure. It contrasts with derivation, which involves forming new words by changing a word's meaning or its part of speech (e.g., adding "-ness" to "happy" to create "happiness," which is a noun instead of an adjective). Lexical inflection, however, focuses solely on grammatical categories.
Key Characteristics and Distinctions
Lexical inflection marks specific grammatical features that help sentences convey precise meaning. These distinctions include:
- Tense: Indicating when an action occurs (e.g., past, present, future).
- Person: Showing who is performing the action (e.g., first, second, third person).
- Number: Differentiating between singular and plural forms.
- Gender: Marking grammatical gender where applicable (less common in modern English for most words).
- Mood: Expressing the speaker's attitude toward the action (e.g., indicative, subjunctive).
- Voice: Indicating the relationship between the verb and its subject (e.g., active, passive).
- Case: Showing a word's grammatical function in a sentence (e.g., subject, object, possessive).
Examples of Lexical Inflection
Different parts of speech undergo various forms of inflection to indicate these grammatical distinctions. Here are some common examples:
| Word Type | Base Form | Inflected Form(s) | Grammatical Distinction(s) |
|---|---|---|---|
| Noun | cat |
cats |
Number (Plural) |
child |
children |
Number (Plural) | |
dog |
dog's |
Case (Possessive) | |
| Verb | walk |
walks |
Person, Number (3rd singular present) |
walk |
walked |
Tense (Past) | |

Aspect (Present Participle) | |
| Adjective | big |
bigger |
Degree (Comparative) |
big |
biggest |

Why is Lexical Inflection Important?
Lexical inflection plays a crucial role in the syntax and semantics of a language. It allows for concise expression of grammatical relationships within sentences, making communication more efficient and unambiguous. For instance, knowing whether a noun is singular or plural, or whether a verb is in the past or present tense, is fundamental to understanding the meaning of a sentence. Without inflection, languages would need to rely more heavily on separate words or strict word order to convey these essential grammatical nuances.
