Somnabulist, calithumpian, rhombidodecahedron aren’t on your everyday elementary school word list. But at Sippican School’s Vocabulary Day, everyone had a new word to share.

Friday was the seventh annual event in which student and teachers used costumes to illustrate new vocabulary words.

Wearing caution tape, a hard hat, and safety orange, fourth grader Tucker Figueiredo was the image of the word circumspect. Tucker said he came up with the outfit by himself.

“I know that warning signs are in flashy colors, so I got some flashy colors,” he said.

Second grader Mackenzie Luong chose "green thumb" as her vocabulary word, and got a curly neon green wig for her costume. “It’s a person that plants a lot of plants, but those plants have to be healthy, green, and tall,” she explained.

For Maeve McEnroe, a sixth grade student, Vocabulary Day is something she’s done for several years. On her final Vocabulary Day, Maeve chose the words knackered, a word she learned in Australia and duvet. A handmade quilt was the perfect combination of the two.

“I had this quilt I had made a couple of weeks ago, and I wanted to wear it because it’s really comfortable,” she said. “My mom wanted me to be knackered, so I decided to have a duvet because I’m knackered.”

Oh and still wondering what somnabulist, calithumpian, rhombidodecahedron mean? Sorry, like the students at Sippican School, you’ll have to look that up in a dictionary.
