お皿
おさら · osara · JLPT N5 · noun
home plate
🍽️ お皿 = polite o + sara (plate); sara sounds like saucer
The o is the honorific prefix that softens everyday nouns, as in ocha (tea) and okane (money). The core word is sara, plate. Sara and saucer both start with the same s-a sound, and a saucer is a small plate.
