Meaning

Semantic Notes
Often used in contrast to 'grammar'. While grammar deals with structure and rules, lexis refers to the inventory of meaningful units. In language teaching, it emphasizes vocabulary as a system rather than isolated words.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'лексис' (a proper name/company in Russian).
- Avoid translating as 'словарь' (dictionary) for objects; it's an abstract concept closer to 'лексика' or 'словарный состав'.
Common Mistakes
- Using 'lexis' to refer to a physical dictionary (that's a 'lexicon').
- Pronouncing it /ˈliːksɪs/ (like 'Leo' with ks). Correct is /ˈlɛksɪs/.
- Using it in non-technical contexts where 'vocabulary' is more appropriate.
