Visual Association
Imagine a tiny sailboat ('velum' sounds like 'sail' in Latin) floating on your tongue—the 'velum' is the soft sail-like flap at the back of your mouth!
Wordplay
Break it down: 'Ve-' (like 'veil') + '-lum' (sounds like 'loom'). Picture a veil woven on a loom covering your throat—just like the velum covers the nasal passage when swallowing.
例句
The velum helps prevent food from entering the nasal cavity during swallowing. (腭帆在吞咽时防止食物进入鼻腔。)
