Quick answer
What does “linked list” mean?
A fundamental data structure in computer science consisting of a linear sequence of nodes, where each node contains data and a reference (a link) to the next node in the sequence.

Meaning and Definition
A fundamental data structure in computer science consisting of a linear sequence of nodes, where each node contains data and a reference (a link) to the next node in the sequence.
In broader contexts, can metaphorically describe any sequential arrangement where elements are connected by explicit pointers or references, facilitating dynamic insertion and deletion but lacking direct random access. Also used conceptually in project management and organizational theory to describe task dependencies.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Potential minor orthographic preference for hyphenation ('linked-list') is inconsistent and not region-specific. Pronunciation differences follow general patterns for the constituent words.
Connotations
Identical technical connotations. In non-technical metaphorical use, both variants carry the same meaning.
Frequency
Virtually identical frequency within technical domains. The term is international technical jargon.

Usage
Meaning in Context
Business
Rare. May appear in technical project planning to describe dependent tasks: 'The project milestones form a linked list of deliverables.'
Academic
Common in computer science, data structures, and algorithm textbooks and research papers. Core curriculum topic.

Common Mistakes When Using “linked list”
- Using 'linked list' as a verb (e.g., 'I will linked list the items' – incorrect).
- Confusing it with an 'array' or 'list' in Python (which are dynamic arrays, not linked lists).
- Misspelling as 'linklist' or 'link-list'.
- Incorrect preposition: 'search on a linked list' instead of 'search in/through a linked list'.
FAQ
Frequently Asked Questions
No, a Python list is a dynamic array, not a linked list. It provides O(1) time for indexing, which a standard linked list does not.
The main types are: Singly Linked List (each node points to the next), Doubly Linked List (each node points to both next and previous), and Circular Linked List (the last node points back to the first).
Use a linked list when you need frequent insertions and deletions at unknown positions (especially the beginning/middle), and you don't need frequent random access by index. Use an array when you need fast random access and know the approximate size in advance.
The 'head' is a reference or pointer to the first node in the linked list. It is the entry point for accessing the entire structure. If the head is null/nil, the list is empty.
A fundamental data structure in computer science consisting of a linear sequence of nodes, where each node contains data and a reference (a link) to the next node in the sequence.
Linked list is usually formal, technical (computer science, software engineering, academic) in register.
Linked list: in British English it is pronounced /ˌlɪŋkt ˈlɪst/, and in American English it is pronounced /ˌlɪŋkt ˈlɪst/. Tap the audio buttons above to hear it.

Idioms & Phrases
- “A chain is only as strong as its weakest link (conceptually related)”
- “To link arms (metaphorical for connection)”
Learning
Memory Aids
Mnemonic
Think of a treasure hunt where each clue (node) tells you where to find the next clue (link), rather than giving you a map to all clues at once (like an array).
Conceptual Metaphor
A CONTAINER IS A CHAIN; DATA STRUCTURES ARE PHYSICAL STRUCTURES (a beaded necklace, a train with coupled carriages).
