lower case
B2Formal, Technical, Academic, Everyday (in specific contexts like computing or writing)
Definition
Meaning
The small letters of an alphabet (as opposed to capital letters), such as a, b, c.
A term used in typography, computing, and writing to refer to letters that are not capitals; can also refer figuratively to something considered less significant or standard.
Linguistics
Semantic Notes
Originally from the printing press era, where the smaller letters were kept in the lower type case. Used as a compound noun ('lower case'), a modifier ('lower-case letter'), or as a verb ('to lower case').
Dialectal Variation
British vs American Usage
Differences
Usage is identical. The hyphenated form 'lower-case' is slightly more common in formal British writing as an adjective, while American English often uses 'lowercase' as a single word, especially in computing contexts.
Connotations
Identical technical and neutral connotations in both varieties.
Frequency
Slightly more frequent in American English due to its prevalence in computing terminology (e.g., 'lowercase string').

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'нижний регистр' in non-computing contexts where 'строчные буквы' is more natural.
- Do not confuse with 'меньший размер' which refers to font size, not letter case.
Common Mistakes
- Writing it as one word when it should be two ('lowercase' vs. 'lower case')—acceptance varies.
