1.adjectiveB2

Common collocations
  • episodic rainfall
  • episodic visits
  • episodic contact
  • episodic outbreaks
Synonyms
  • intermittent

    more technical; often used for symptoms or signals that stop and start

  • occasional

    weaker intensity; 'occasional' suggests rarity rather than irregular pattern

  • sporadic

    implies even less predictability; 'sporadic' suggests random occurrence

Antonyms
  • regular

    happening at fixed, predictable intervals

  • continuous

    happening without interruption

Grammar Patterns

episodic + noun (episodic visits, episodic rain)

be + episodic

Usage Note

Often describes things that are expected to be regular but are not — like rainfall, visits, or public services. Distinguish from sense 3 (loosely connected events, not irregular timing).

Common Mistakes

The episodic rain lasted all day without stopping.
The rain was continuous, not episodic.
'episodic' means irregular and intermittent, not non-stop.

2. (of a story, show, or programme) told or presented in separate parts or episodes

2.adjectiveB2
Definition

(of a story, show, or programme) told or presented in separate parts or episodes, especially one part at a time on television, radio, or streaming platforms.

Example

The new detective series has an episodic structure where each episode solves a different crime while the main characters' personal story continues throughout the season.

episodic + structure: each episode is self-contained but linked

Dr. Okafor prefers episodic podcasts because she can listen to any single episode without needing to follow a long, continuous story.

Common collocations
  • episodic television
  • episodic format
  • episodic storytelling
  • episodic drama
Synonyms
  • serialized

    similar but implies stronger overarching plot connecting episodes

  • segmented

    more general; can refer to any divided structure, not just media

Antonyms

Grammar Patterns

episodic + noun (episodic story, episodic series)

Usage Note

Typically describes TV shows, radio dramas, podcasts, and web series. The opposite is 'serial' (one continuous story across episodes) or 'non-episodic'.

Common Mistakes

The film was episodic, with a single story from start to finish.
The film was not episodic
it told one continuous story.' — a non-episodic work tells a single unbroken narrative.

3. made up of separate events, scenes, or memories that are only loosely connected

3.adjectiveC1
Definition

made up of separate events, scenes, or memories that are only loosely connected and do not form one smooth, continuous whole.

Example

The old man's account of his youth was episodic — he jumped from one vivid memory to another without following a clear timeline.

episodic + memories/account: loosely connected fragments

The novel uses an episodic structure, moving between different characters' perspectives in short, self-contained chapters.

Common collocations
  • episodic narrative
  • episodic memory
  • episodic structure
  • episodic adventures
Synonyms
Antonyms

Grammar Patterns

episodic + noun (episodic narrative, episodic memories)

be + episodic (in structure)

Usage Note

In psychology, 'episodic memory' is a technical term for the ability to recall specific personal experiences. This sense differs from sense 2 (intentionally divided for TV/radio) by focusing on the loose, fragmentary quality of the content itself.

Common Mistakes

The movie was episodic because it was shown in three parts on different nights.
That movie was shown in episodes
it had an episodic release. Its story was also episodic, jumping between unrelated scenes.' — sense 2 (media format) and sense 3 (loose structure) are different.

4. happening as a single, short-lived event that does not continue or become perman

4.adjectiveC1
Definition

happening as a single, short-lived event that does not continue or become permanent — limited to one episode in time.

Example

The patient's fever was episodic, spiking to 39 degrees for one night and then disappearing completely the next day.

episodic + fever: a single, short-lived occurrence

The night-shift nurse warned that the dizziness might be episodic, lasting only while the medication entered her system.

Common collocations
  • episodic pain
  • episodic fever
  • episodic symptoms
  • episodic difficulties
Synonyms
  • temporary

    more common and broader; lacks the 'single event' focus

  • transient

    more formal; emphasizes the short duration

  • brief

    simpler and more general

Antonyms
  • permanent

    lasting indefinitely

  • chronic

    long-lasting or recurring over a long period

Grammar Patterns

episodic + noun (episodic fever, episodic pain)

be + episodic

Usage Note

This is the least common sense. Often found in medical or technical writing about symptoms or conditions that come and go. Distinguish from sense 1 (repeated irregular occurrences) — this sense emphasizes a single occurrence that is temporary, not a pattern of irregular events.

Common Mistakes

The episodic rain returned every afternoon for a week.
The rain followed a pattern
that is sense 1, not sense 4.' — sense 4 describes a single temporary episode, not repeated irregular occurrences.

Synonym discussion

Sense: adjective/1

All four words describe things that do not happen steadily, but they emphasise different aspects. 'Occasional' is the mildest and most common — it simply means 'sometimes but not often' and carries no judgement about predictability (e.g. 'occasional visits to the dentist'). 'Intermittent' is more technical and implies a stop-start pattern, often used for signals, symptoms, or machinery (e.g. 'intermittent Wi-Fi connection'). 'Sporadic' suggests random, scattered occurrence with no rhythm at all (e.g. 'sporadic gunfire in the distance'). 'Episodic' (sense 1) overlaps with 'sporadic' but adds the idea that the occurrences come in distinct, separate blocks or episodes rather than as isolated events. For example: 'His episodic outbursts of anger would last an hour each time' — each block is an episode. 'Irregular' is broader and includes any deviation from a norm, whether the pattern is predictable or not. Choose 'episodic' when the key idea is that events arrive in defined chunks rather than as a smooth or predictable stream.

Etymology

GreekLatinFrenchEnglish

Derived from the Greek 'episodion' (ἐπεισόδιον), meaning 'a coming in besides' or 'an addition'. In ancient Greek theatre, an 'episode' was the part of a play between choral songs — a self-contained segment within the larger drama. Latin borrowed it as 'episodium', and French passed it into English as 'episode' in the 17th century. The adjective 'episodic' appeared in the early 1800s, first describing literary works made up of loosely connected episodes, then broadening to cover any irregular, intermittent, or temporary phenomenon.
