In corpus-based analysis, which of the following is primarily used to identify the frequency and distribution of words or phrases across large collections of texts?

Correct option is C

Explanation

The correct answer is Option 3: Concordance lines.

In corpus linguistics, concordance lines are one of the most important tools for examining how words or phrases occur across large collections of texts. A concordance displays multiple instances of a searched word or phrase in its immediate context, usually in a KWIC format (Key Word in Context). By looking at many occurrences together, researchers can identify patterns of frequency, distribution, grammatical behavior, and contextual meaning.

Concordance lines allow scholars to see where a word appears, what words commonly surround it, how it functions in sentences, and whether usage changes across genres or speakers. Because they provide repeated contextual examples drawn from large corpora, they are central to corpus-based frequency and distribution studies.

What is Corpus Linguistics?

Corpus linguistics is the study of language through large digital collections of authentic texts called corpora. Instead of relying only on intuition, researchers analyze real language data.

What Concordance Lines Show

If we search the word issue, concordance lines may show:

environmental issue
issue of identity
raise an issue
serious issue

This helps identify:

Frequency
Distribution
Repeated patterns
Register differences
Semantic prosody
Famous Corpora
British National Corpus (BNC)
Corpus of Contemporary American English (COCA)
Brown Corpus
ICE (International Corpus of English)
Uses
Lexicography (dictionary making)
Language teaching
Stylistics
Discourse analysis
Translation studies
Sociolinguistics
Summary

Concordance lines are essential because they make large-scale language patterns visible through real examples.
