- Misplacing stress on the first syllable: LA-cunae. Correction: stress the second syllable (la-CU-nae) and produce /juː/ before the final vowel. - Slurring the /kj/ into /k/ or /j/: ensure a crisp /k/ followed by /juː/. Use a small delay between /k/ and /juː/. - Ending with a short vowel: avoid /nɪ/ or /nə/; use a long final vowel /niː/ or /neɪ/ based on target accent. - Final vowel variability: decide between /niː/ and /neɪ/ consistently in the given context to maintain intelligibility.
How to Pronounce Lacunae
"The histologist observed numerous lacunae within the bone matrix."
"There are several lacunae in the manuscript where the original text was lost."
"The researcher noted research lacunae that future studies should address."
Break it as la-KU-nae, with primary stress on the second syllable: la-KYOO-nay in US and UK IPA as /ləˈkjuːniː/ or /ləˈkjuːneɪ/ depending on accent. Start with a clear 'l' then a light schwa, then an emphasized 'kyoo' (like 'cue'), and finish with a long 'nee' or 'nay' depending on region. Listen for the final long vowel in medical contexts; you’ll hear variants /niː/ or /neɪ/.
Mistakes include misplacing the stress on the first syllable (LAH-kyoo-nə) or pronouncing the second syllable as /ləˈkjuːnæ/ with a short vowel. Another error is merging the vowel into a single syllable (la-OO-na). Correction: maintain secondary syllable stress on KU, use a clear /juː/ sequence for 'cue', and end with a long /iː/ or /eɪ/ depending on the speaker’s accent.
In US: /ləˈkjuːniː/ with rhotacized vowel in some dialects and a clear /juː/ sequence. UK: /ləˈkjuːneɪ/ tending to a longer final diphthong /eɪ/. Australian: often /ləˈkjunaɪ/ or /ləˈkjuːniː/, with less rhoticity and a flatter final vowel. Focus on the /juː/ blend after /k/ and the final long vowel; variation is mainly in the final vowel quality and syllable nucleus length.
Challenges include the unstressed initial schwa, the consonant cluster /kj/ after /l/, and the final long vowel, which can be realized as /iː/ or /eɪ/ depending on dialect. The tricky part is maintaining a crisp /k/ preceding /juː/ and not slurring into /kuːi/. Practice differentiating /k/ + /juː/ and finishing with a stable high-front vowel.
The plural end -ae signals the Latin plural; in English the pronunciation remains /-aɪ/ or /-iː/ depending on academic convention, but most modern usage favors /niː/ or /neɪ/ at the end. Pay attention to the second syllable’s stress and the final long vowel; you will hear subtle regional shifts in academic contexts.

Lacunae comes from Latin lacuna, meaning a hollow, cavity, or gap. The singular lacuna originates from Latin lacuna, itself from lacus meaning a hollow or pit; the plural form lacunae follows Latin second declension feminine noun endings. In anatomy and biology, lacunae describe small cavities in tissues like bone or cartilage that house cells such as osteocytes, which reside in lacunae and communicate through gap junctions. The term entered scientific English through medical Latin usage during the Renaissance and early modern era as scholars documented microscopic and macroscopic structures. Its broader figurative sense—any gap or missing portion in a body of knowledge or a text—emerged in later scholarly prose as metaphorical extension of the anatomical idea of a hollow space. First known use in English citations aligns with anatomical texts of the 17th–18th centuries, reflecting its Latin roots and continued relevance in modern anatomy and paleontology.
