2 syllables: out, crop. Stress on out.
/ˈaʊt.kɹɑp/
Say it backOutcrop is a rock exposure at the surface where underlying geology is visible. It refers to any surface rock that stands out from surrounding material, often revealing the mineral composition and structure of the subsurface. In geology, outcrops provide crucial clues about past environments and tectonic history, and the term is used in field notes and maps to describe exposed rock faces or ledges.
"The field geologists mapped the village’s outcrop to understand the regional sedimentary layers."
"During the hike, we stopped at an outcrop to study the hard, resistant limestone."
"The road cut revealed an outcrop rich in fossil fragments."
Pronounce as /ˈaʊt.kɹɒp/ in US and UK; in Australian English you’ll hear /ˈaʊt.kɹɒp/. The primary stress is on the first syllable: OUT-crop. Start with the diphthong /aʊ/ as in ‘now,’ then a crisp /t/, then /kɹ/ (a light ‘cr’ sound), and end with /ɒp/ like in ‘cot’ but with a rounder vowel before the final /p/. Audio references: you can compare with standard dictionaries or YouGlish for word-by-word usage.
Common errors include softening the /t/ into a glottal stop in rapid speech, misplacing the /r/ or making it non-rhotic, and shortening the second syllable to /ɒ/ without the following /p/. To correct: clearly articulate /t/ as a stop, pronounce the /r/ as a light retroflex approximant [ɹ], and ensure the final syllable is /ɒp/ with a true stop at the end. Practice with min-pairs and emphasis on the initial diphthong /aʊ/.
In US and UK rhotic varieties, the /ɹ/ is pronounced before the vowel in /ɹɒp/; in non-rhotic UK accents you might hear a weaker or less pronounced /ɹ/ before the vowel, but in this word the /ɹ/ is usually present. Australian English tends to keep /ɹ/ similar to US, but with slightly different vowel quality in /ɒ/. Overall, stress remains on the first syllable, with /aʊ/ as a prominent diphthong across dialects.
The difficulty lies in the cluster /ktɹ/ between the two syllables: you move from the diphthong /aʊ/ into a /t/, then a /k/ followed by /ɹ/, which can blur in fast speech. Additionally, achieving a crisp final /p/ after a strong vowel requires precise plosive timing. The rhotic /ɹ/ can also vary by accent, affecting perceived clarity. Focus on articulatory timing and a clean release of each consonant.
A unique query centers on the transition from /t/ to /k/ and the presence of /ɹ/ between them: /aʊt.kɹɒp/. You’ll hear or feel a small spring-stop between the /t/ and /k/ with a light /ɹ/ onset. Practicing the sequence /aʊt/ followed by /kɹ/ helps you keep the plosive stops distinct and prevents blending. Also note that preceding vowels tend to be tense, with minimal vowel lowering in careful speech.

The word outcrop combines out- from Old English ut (outside, outward) with crop from Middle English croppe (a tuft or projection, later rock). The sense evolved in geology to denote rock that crops out of the ground, i.e., stones that become visible at the surface. First attested in the 18th–19th centuries, the term reflects a practical field observation: rocks that “crop” into view against soil or vegetation during surveying. Over time, “outcrop” became a standard term in geology and mining, used in field notes, maps, and descriptions of terrain. The concept likely has parallels in other languages that describe rocky exposures appearing at the surface due to erosion, uplift, or faulting, but the English usage solidified in scientific geology as a precise label for surface-visible rock formations. In modern usage, outcrop denotes the visible face of bedrock regardless of rock type, with modifiers indicating quality or extent (e.g., limestone outcrop, sandstone outcrop, broad outcrop).
