1.adjectiveC2
Definition

Relating to languages in which words change their form — by adding endings or changing a vowel, for example — to show grammatical functions such as tense, number, case, or gender.

Example

Latin is a highly inflective language where noun endings show whether a word is the subject or the object.

collocation: highly inflective + language

Niran found it hard to learn Russian because it is an inflective language with many different word forms.

Common collocations
  • highly inflective
  • inflective language
  • more inflective
  • inflective system
Synonyms
  • inflectional

    The more common term; 'inflectional' can describe both languages and individual endings, while 'inflective' is less common and mostly limited to languages as a whole.

  • synthetic

    A wider linguistic category; synthetic languages use inflection AND agglutination, so 'synthetic' is broader than 'inflective'.

  • fusional

    Describes languages where a single ending carries multiple grammatical meanings at once; a subtype of inflective languages.

Antonyms
  • analytic

    Describes languages that use separate words (like prepositions or auxiliary verbs) instead of word-form changes.

  • isolating

    A language where each word typically has a single morpheme and no inflectional endings at all, such as Mandarin Chinese.

Grammar Patterns

inflective + noun (language)

Usage Note

Typically used to describe whole language systems rather than individual word forms. For individual endings or markers, the more common term is 'inflectional' (sense 2).

Common Mistakes

Spanish is an inflective language with many verb forms.
Spanish is a highly inflective language with many verb forms.
'highly' is a common and natural intensifier for 'inflective' in linguistics writing.

2. Describing a grammatical marker such as an ending or suffix that changes a word'

2.adjectiveC2
Definition

Describing a grammatical marker such as an ending or suffix that changes a word's form to show its grammatical role — tense, number, case, or person — rather than creating a completely new word with a different meaning.

Example

The suffix '-ed' is an inflectional ending that shows a verb happened in the past.

pattern: inflectional + ending/suffix/marker

Caleb learned that '-s' can be an inflectional marker for both plural nouns and third-person verbs in English.

Common collocations
  • inflectional ending
  • inflectional suffix
  • inflectional marker
Synonyms
  • inflectional

    The standard and far more common term; 'inflectional ending' is the ordinary way to describe affixes that mark grammar.

  • grammatical

    Broader — covers all grammar-related elements, not just inflection; e.g. grammatical markers include word order, particles, and function words.

Antonyms
  • derivational

    Describes affixes that create new words with different meanings (e.g. '-ness' turns 'happy' into 'happiness'), whereas inflective endings only change the grammatical form of the same word.

Grammar Patterns

inflectional + noun (ending, suffix, marker)

Usage Note

This sense overlaps heavily with 'inflectional', which is far more common in modern academic writing. Reserve 'inflective' for contexts where the alternative would sound imprecise or clumsy.

Common Mistakes

The word "walked" has an inflective ending "-ed".
The word "walked" has an inflectional ending "-ed".
'inflectional' is the standard adjective for individual grammatical markers; 'inflective' sounds dated or overly technical in this use.

Synonym discussion

Sense: adjective/1

These terms describe different ways that languages encode grammatical relationships. 'Inflective' and 'inflectional' are very close in meaning, but 'inflectional' is far more common — both in academic writing and general reference — and can describe individual endings ('inflectional suffix') as well as whole languages. 'Synthetic' is a broader category that includes both inflective languages (like Latin, where endings fuse multiple meanings) and agglutinative languages (like Turkish, where each grammatical meaning has its own separate marker). 'Fusional' is a subtype of inflective language where a single ending carries several grammatical meanings at once — for example, the Latin ending '-o' can mean 'first person / singular / present / indicative'. For a learner, 'inflectional' is the safest everyday choice; 'inflective' sounds more technical and old-fashioned, and 'fusional' is a specialist term for advanced study.

Etymology

LatinFrenchEnglish

From Latin 'inflectere' (to bend in or curve), formed from 'in-' (in, into) + 'flectere' (to bend). In ancient grammar, the idea of 'bending' a word into different shapes was used as a metaphor for changing word forms by adding endings. The English adjective 'inflective' dates from the early 1700s and was adopted by linguists to describe languages whose grammar relies on this kind of word-form bending.
