How to Pronounce Lacuna

Lacuna is pronounced lah-KYOO-nah. Say it like you're saying 'la' (as in 'la la la'), then 'kyoo' (like the letter Q), and finish with 'nah' (rhymes with 'spa'). The stress falls on the middle syllable: KYOO.

The second syllable gets the stress: lah-KYOO-nah. A common mistake is putting the stress on the first or last syllable, but the emphasis should land squarely on 'KYOO' in the middle.

Lacuna breaks into three syllables: la-cu-na. When you say it slowly, you'll hear each part clearly: la (like 'la' in 'lava'), cu (like 'cue'), and na (like 'nah').

Lacuna comes from Latin and means 'lake' or 'gap.' Scientists chose this word because bone cells sit in tiny pockets within the bone, like little islands in a lake—the empty space is the 'lacuna.'

A lacuna is a tiny hollow space or pocket. In bone anatomy, it's a small cavity where a bone cell (called an osteocyte) fits snugly inside the hard bone material around it.

You might hear 'lacunar' (the adjective form, pronounced lah-KYOO-nar), which means 'relating to a lacuna.' There's also 'lacunae' (pronounced lah-KYOO-nee), which is simply the plural of lacuna—more than one cavity.

Sure! Here's an example: 'Under the microscope, you can see the lacunae in bone tissue where individual bone cells are located.' Another way to say it: 'Each lacuna holds one osteocyte, keeping the bone structure organized.'

The plural is 'lacunae' (pronounced lah-KYOO-nee), which comes from the Latin plural form. In medical writing, you'll see both 'lacunae' and the English plural 'lacunas,' though 'lacunae' is more common in anatomy texts.
