Correlation is pronounced kaw-ruh-LAY-shuhn (/ˌkɔɹəˈleɪʃən/). It has four syllables (Cor-rel-a-tion), with the stress on "a". Correlation is a statistical measure that expresses how strongly pairs of variables are related. It indicates both the strength and direction of a linear relationship, usually quantified by a correlation coefficient. In common language, it signals whether two things tend to move together or apart, without implying causation.

- Misplacing primary stress on the second syllable (cor-RE-la-tion). Correction: mark the third syllable as the nucleus: cor-re-LA-tion and practice saying the entire word slowly before speeding up. - Running the /ˈleɪ/ into a quick /lɛ/ or /lɪ/; keep the diphthong /eɪ/ clear. Correction: exaggerate the /eɪ/ moment in isolation, then blend. - Dropping the final unstressed /ən/ or turning it into an /ənˈ/ that bleeds into the next word; keep it light and short: /ən/. Practice: say 'correlation is...' with a brief pause after -tion to avoid trailing vowels.
"Researchers examined the correlation between exercise frequency and blood pressure."
"There is a positive correlation between education level and income in the dataset."
"The scatterplot shows a strong negative correlation between age and reaction time."
Pronounce as ˌkɔːrəˈleɪʃn̩ in careful speech, or /ˌkɒrɪˈleɪʃən/ in US usage. Stress sits on the third syllable: cor-re-LA-tion, with the main syllable force on -la-; the final -tion is unstressed. Keep the 'cor' as /ˈkɔr/ or /ˈkɒr/ depending on accent, plus a clear /leɪ/ vowel. You’ll often hear a slight linking from /r/ into /ə/ before /ˈleɪ/ in connected speech. IPA: us /ˌkɔːrəˈleɪʃən/, uk /ˌkɒrəˈleɪʃən/, au /ˌkɒrəˈleɪʃən/.
Two main issues: misplacing the stress and compressing the -leɪ- into a quick /lə/; or pronouncing the final -tion as /tʃən/ instead of /ən/. Correction: place primary stress on the third syllable: cor-re-LA-tion; use /ˈleɪ/ for the vowel sequence; end with a clear /ən/, not /tən/. Practice with minimal pairs focusing on -leɪ- vs -li- and ensure the final syllable is light and unstressed.
In US, /ˌkɔːrəˈleɪʃən/ with rhotic /r/ and clearer /ɔː/ in 'cor'. UK typically uses /ˌkɒrəˈleɪʃən/ with shorter /ɒ/ and non-rhotic follow-through in some speakers, though many use rhotic varieties. Australian often follows US rhythm but with a flatter /ɒ/ or /ɔ/ in the first syllable and clear /ˈleɪ/ in the third; final -tion remains /ən/. Across all, primary stress remains on the third syllable: cor-re-LAY-tion. IPA references: US /ˌkɔːrəˈleɪʃən/, UK /ˌkɒrəˈleɪʃən/, AU /ˌkɒrəˈleɪʃən/.
Because it combines a dense cluster of sounds: an initial /k/ followed by /ɔː/ or /ɒ/ and a rhotic or semi-rhotic r, plus the long /eɪ/ diphthong in -leɪ-, and finally an unstressed /ən/ after a stressed syllable. The sequence cor-re-LAY-tion can trip nonnative speakers on syllable timing and vowel length, especially in fast speech. Working on the /ɔː/ vs /ɒ/ distinction, keeping the /ˈleɪ/ intact, and landing the /ən/ clearly helps with natural pronunciation.
Correlation has no silent letters; every letter contributes to the pronunciation. The challenge is not silent letters but the multi-syllabic rhythm: COR-re-LA-tion with stress on -LA-. The 'tion' ending is pronounced as /ʃən/ in some words, but in correlation it’s the weaker /ən/ ending. You’ll also want to relax the jaw between cor and rela- to avoid a clipped transition.

- US: /ˌkɔːrəˈleɪʃən/ with rhotic r; stress on -LA-. Vowel in 'cor' is broad /ɔː/. - UK: /ˌkɒrəˈleɪʃən/ with short /ɒ/ and non-rhotic syllable r if following consonant letter; still stress on -LA-. - AU: /ˌkɒrəˈleɪʃən/ tends toward /ɒ/ in 'cor' and a clear /ˈleɪ/ in the third. All share the same stress pattern; practice rhoticity awareness and give emphasis to -LAY- while keeping final /ən/ light. IPA: us /ˌkɔːrəˈleɪʃən/, uk /ˌkɒrəˈleɪʃən/, au /ˌkɒrəˈleɪʃən/.
Correlation derives from the Latin verb corrēlārī, meaning to reckon together, from 'con-' (together) and 'rēlārī' (to relate). The noun form entered English in the early 19th century in mathematical contexts, evolving from ‘correlate’ (to relate) plus the abstract noun suffix '-ation' to denote a quantified measure of the degree to which two variables change together. The concept gained prominence with the development of statistics, particularly around Pearson’s correlation coefficient in the late 19th and early 20th centuries. The term has broadened in social sciences, natural sciences, and data analytics to describe any demonstrated association between two quantitative measures, while remaining distinct from notions of causation. Today, correlation is ubiquitous in research reporting, machine learning feature analysis, and risk assessment, often accompanied by the coefficient r that ranges from -1 to 1, with 0 indicating no linear relationship.
