You pronounce it as /kəˌrɒb.əˈreɪ.ʃən/ in UK and /kəˌrɑː.bəˈreɪ.ʃən/ in US, with the primary stress on the third syllable -o-RA-tion. Break it into cor-ro-bo-ra-tion, but emphasis lands on the -ra- in the third-to-last syllable. Tip: the sequence contains an /ɒ/ (UK) or /ɑː/ (US) in the second syllable and a clear /ˈreɪ/ vowel in the fourth. Audio reference: web pronunciations linked from Pronounce and major dictionaries will illustrate the gradual rise on the /reɪ/ with a trailing schwa before /ʃən/.
Common errors include flattening the second syllable to /ə/ or /ɒ/ without distinguishing /rb/ sequence, and misplacing the main stress on the second or fourth syllable. Some speakers blurt the /ˈreɪ/ too early or merge /ˌkɒr-ɒ-/. Correction: segment as /kəˌrɒb.əˈreɪ.ʃən/ (UK) or /kəˌrɑː.bəˈreɪ.ʃən/ (US) and emphasize the /ˈreɪ/ syllable with a short, crisp consonant release before /ʃən/. Practicing with minimal pairs and listening to native models helps fix rhythm and stress.
In US, the /ɚ/ in -ro- is often a rhotacized vowel; the /ɒ/ becomes /ɑː/ in many dialects, and /ˈreɪ/ tends to be clear. UK pronunciation uses /ˌkɒrəˈbeɪːrəs/ in some dialects, but standard is /kəˌrɒ.bəˈreɪ.ʃən/. AU tends to merge certain vowels, with non-rhotic r and slightly flatter vowels, so /kəˌɹɒ.bəˈɹeɪ.ʃən/ is common. The key is maintaining the /r/ after the initial vowel and delivering the stressed /ˈreɪ/ clearly, with variations mainly in vowel quality and rhoticity.
Difficulties come from the multi-syllabic length, the sequence /ˌrɒb.əˈreɪ.ʃən/ with two adjacent unstressed syllables and a final -tion, which can become /ʃən/ or /ən/ depending on speech rate. The /r/ cluster after a short /ə/ can blur if you don’t separate syllables, and the /ˈreɪ/ vowel must be crisp to avoid blending into /ˈreb/ or /rə/. Practice ensures each segment is distinct: cor-rob-o-ra-tion, with precise /r/ and /ˈreɪ/.
Yes. The primary stress lands on the third-to-last syllable: cor-rob-o-RA-tion, that is /ˌkəˌrɒb.əˈreɪ.ʃən/. The syllable timing leans toward a trochaic-to-dacritic rhythm, where the third-from-last carries the emphasis and the preceding segments lead into it. This makes it noticeably longer on -ra- than on the initial syllables, and you should slow slightly before /reɪ/ to land the main stress clearly.

Corroboration comes from the Late Latin corroboratio, from corroborare ‘to strengthen, reinforce,’ which itself is from Latin com- ‘with, together’ + robur ‘strength.’ The term entered English in the 16th–17th centuries in legal and scholarly contexts, originally describing the act of strengthening a claim with additional evidence or testimony. Over time, corroboration broadened to general verification across disciplines, including science, journalism, and everyday argumentation. The core idea remained consistent: the addition of independent support to reduce doubt and increase reliability. The word is tied to concepts of reliability, corroborative evidence, and mutual reinforcement among multiple sources. First known usages appear in legal and academic texts of Early Modern English, reflecting a burgeoning emphasis on evidentiary integrity and cross-verification in inquiry and adjudication.
