2 syllables: black, hole. Stress on black.
/ˈblækˌhoʊl/
Say it backA black hole is a region of space where gravity is so intense that nothing, not even light, can escape from it. In physics, it represents a boundary beyond which events cannot affect an outside observer. The term is often used metaphorically to describe something irresistibly absorbing or inescapable.
"Scientists study the event horizon and accretion disk of a black hole to understand extreme gravity."
"The concert venue became a black hole for my wallet after I bought premium tickets."
"Her focus on the project was a black hole for distractions, pulling her attention in completely."
You say /ˈblækhoʊl/. It’s a two-syllable word with primary stress on the first syllable: BLÆK-hoʊl. Start with /bl/ as in blue, open /æ/ like cat, then the second syllable contains /hoʊl/ with a long O, like hole. In many contexts, especially casual speech, it can be pronounced as two words: /ˈblæk hoʊl/. Audio references: consult standard dictionaries and platforms like Forvo for native speaker examples.
Common errors include reducing the /æ/ to a schwa in the first syllable (bləkhole) and truncating the second syllable to a quick /l/ or /oʊl/ without the clear /hoʊ/ portion. Another pitfall is stressing the second syllable instead of the first. To correct: keep /æ/ clearly as in 'cat' and ensure the /hoʊl/ is a distinct, rounded long vowel with a rounded lips and a clear final /l/ release.
US tends to maintain a strong first-syllable /æ/ and a clear /hoʊl/, with non-rhoticity not affecting the /l/ at the end. UK often has a slightly lighter /ə/ in fast speech before the /l/, producing /ˈblækhəʊl/ with a shorter before-l vowel. Australian tends to reduce unstressed vowels a touch less than UK, still preserving /æ/ in the first syllable and a rounded /oʊ/ in the second, but with subtle vowel colouring characteristic of AU. Always listen for the vowel quality and rhythm differences.
The difficulty lies in layering two phonemes: /æ/ in the stressed first syllable and the long /oʊ/ in the second, which can blend in rapid speech. The final /l/ requires precise tongue tip contact and a clear release. For non-native speakers, coarticulation with the /h/ in the middle can blur the boundary between syllables. Practice by isolating /æ/ and /hoʊl/ and building a fluid transition between them.
There is no silent letter in standard pronunciation of 'blackhole'. All letters in both syllables contribute to the sound: /b/ initial, /l/ onset cluster, /æ/ vowel, /k/ release, then /h/ onset for the second syllable with /oʊ/ and final /l/. The middle /h/ is not silent; it helps separate the consonant cluster at the syllable boundary and aids the glottal and aspirated influences.

The term black hole originated in the mid-20th century in discussions of astronomical theory, though elements of the concept existed earlier in physics discussions about singularities. The earliest roots lie in the word black used in astronomy to describe darkened regions, and hole as a metaphor for an absence or void. In the 1960s, theorists described regions where escape velocity exceeds light speed as gravitationally trapped, coining the practical shorthand ‘black hole’ to convey both darkness and inescapability. The phrase captured popular imagination as equations from general relativity, notably by Albert Einstein, predicted regions where gravity would swamp all other forces. First widely credited usage appears in scientific prose and later in popular science writings and journalism, solidifying ‘black hole’ as both a physical object and a metaphor for irresistibly absorbing phenomena.
