C1formal, academic, technical
Definition
Meaning
relating to, serving as, or containing an index; pointing out or indicating something.
In linguistics and philosophy, an indexical is a word or expression (like 'I', 'here', 'now', 'this') whose meaning depends on the specific context of its use, i.e., who says it, where, and when. As an adjective, it can also describe something that is characteristic or indicative of a specific context.
Linguistics
Semantic Notes

Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как 'индексный' (relating to a database index). Ближе по смыслу 'указательный' или 'контекстуально-зависимый'.
- Не путать с 'index' в значении 'показатель'. 'Indexical' — это характеристика слова или знака, а не числовой показатель.
Common Mistakes
- Using 'indexical' to mean 'relating to a book index'.
- Confusing 'indexical' with 'indicative' in non-technical writing where 'indicative' is more natural.

FAQ
Frequently Asked Questions
No, it is a highly specialised academic term used primarily in linguistics, semiotics, and philosophy.
In linguistics, they are often used synonymously. Some scholars use 'deictic' more for words directly pointing to person, place, or time ('I', 'here', 'now'), and 'indexical' more broadly for any sign (including non-linguistic) that indicates a state of affairs (smoke indexing fire).
It would sound very unnatural and confusing. In everyday contexts, use words like 'indicative', 'characteristic', or 'typical of' instead.
The noun is 'indexicality', referring to the property of being indexical (e.g., 'The indexicality of language is a key topic in pragmatics').
