How do you define J-O-C-U-L-A-R-I-T-Y? The literal translation is “The 25^th Annual Putnam County Spelling Bee,” now playing at Stray Dog Theatre.

A splendid summer sojourn, the jaunty musical comedy celebrates American traditions and meritocracy, our inherent competitive spirt, and freak-flag waving.

At a nondescript middle school, a sextet of smarty-pants sixth graders competes for a $200 savings bond and a towering trophy at the annual big-deal event. Three adults handle the proceedings, and four audience members are selected to participate, too.

And the blithe spirits on stage and in the audience instinctually know this is far more pleasurable than Mensa members getting together for Scrabble, especially with its clever audience-participation cachet.

However, those who didn’t make the honor roll need not worry, for SAT scores aren’t required at the door, and it’s a very accessible and inclusive work. The catchy music and savvy lyrics by William Finn (“Falsettos,” “A New Brain”) and the whip-smart Tony-winning book by Rachel Sheinkin offer something for everyone.

In this enjoyable production, adroitly directed by Justin Been, the dexterous cast has mastered the nimble word play and spit-take worthy improvisations for a rollicking good time. They got game.

The in-sync ensemble expertly colors outside the lines, shading their idiosyncratic characters with humor and humanity. Unlike “You’re a Good Man, Charlie Brown,” where grown-ups also play kids, this is a show with mature content.

Kevin Corpuz is returning champ Charlito “Chip” Tolentino, a strident Boy Scout who is struggling with puberty and distracted by a female in audience; Grace Langford is resolute newcomer Olive Ostrosky, whose mom is in India and dad is always working; and Sara Rae Womack is fervid Marcy Park, an over-achieving transfer student.

Clayton Humburg is mellow Leaf Coneybear, home-schooled son of hippies; Dawn Schmid is high-strung Logainne “Schwartzy” SchwartzandGrubenierre, politically aware and pushed by her two dads to win at all costs; and Kevin O’Brien is last year’s egghead finalist William Morris Barfee, whose name is really pronounced Bar-Fay, because of an accent aigu, and not Bar-Fee, like the announcer repeats.

While everyone’s comic timing is admirable, O’Brien elicits many laughs as he embodies a know-it-all misfit unfortunately hampered by one working nostril. Hunching his shoulders, rolling his eyes, and sighing in exasperation, O’Brien is in his element. He has the most peculiar way of spelling out the words – with his “Magic Foot.”

Barfee is one of those supporting roles that is an awards nomination magnet, like Adolfo in “The Drowsy Chaperone” and the UPS guy in “Legally Blonde – The Musical.” Dan Fogler, now of “Fantastic Beasts” who recently played Francis Ford Coppola in “The Offer,” won a Tony Award for originating the role.

The middle-school spellers are joined by four individuals that have volunteered for the gig – signing up in the lobby beforehand.  Good sports, they are called on to spell, without any special treatment, which is a key element to the fun. They might have to spell Lysergic Acid Diethylamide, or cow.

The three adults in the room include ‘comfort counselor’ Mitch Mahoney (Chris Kernan), an ex-con who gives the eliminated contestants a juice box and a hug; former champ and returning moderator Rona Lisa Peretti (Stephanie Merritt), a successful realtor who enjoys reliving her glory days; and Vice Principal Douglas Panch (Jason Meyers), who has returned as a judge after personal time off to work out some ‘things.’

Their perspicacity is evident – and the three veterans are oh-so-smooth with the innuendos and deadpan humor. Merritt is guileful as the supremely assured and unflappable announcer – think Patty Simcox from “Grease” as an adult.

She glibly describes the contestants with seemingly innocent comments and a few double-entendres. You don’t want to miss a word, for you might do a double-take (Wait – what?).

Hilarity ensues whenever the puckish Meyers wryly uses a word in a sentence or describes his feelings. He elevates the script’s wit (those inappropriate comments!) with his crackerjack delivery. Just don’t get him started on Klondike’s decision to drop the Choco Taco! He’s a tad jittery.

Several performers double as ancillary characters, such as parents – for instance, Kernan and Humburg are Logainne’s importunate fathers. Corpuz shows up as Jesus Christ. (You’ll just have to see).

The convivial show, workshopped into an off-Broadway hit, transferred to Broadway in 2005 – and was nominated for six Tony Awards, winning two. It was originally conceived by Rebecca Feldman and based upon “C-R-E-P-U-S-C-U-L-E,” a play by her improv collective, The Farm. Additional material was supplied by Jay Reiss.

The ingenious construction has managed to keep it fresh 17 years later by relying on the actors to be on the ball with au courant references.

Been astutely uses the state of play as an advantage, maintaining a balance of friskiness and sweetness that makes sure everyone is in on the jokes. No mean-spirited sarcasm here.

The cast’s exemplary improv skills make this a very funny, free-wheeling show. But let’s not forget the music is an integral part, too, and each character nails a signature song. Besides Barfee’s “Magic Foot,” there is — Leaf: “I’m Not That Smart.” Olive: “My Friend, The Dictionary.” Marcy: “I Speak Six Languages.” Logainne: “Woe Is Me.” Chip: “Chip’s Lament.”

Rona’s “My Favorite Moment of the Bee” is a running theme throughout, Mitch serenades the last audience speller with “Prayer of the Comfort Counselor,” and Panch is in “Spelling Montage.”

The troupe’s strong voices harmonize well in the group numbers, too.

Music Director Leah Schultz smoothly keeps the tempo on track, and is on piano, joined by Kelly Austermann on reeds and Joe Winters on percussion. Choreographer Mike Hodges keeps the moves light-hearted and breezy.

Jacob Baxley’s sound design enhances Rona’s championship spotlight, as does Tyler Duenow’s lighting design.

Eileen Engel’s costume designs distinctly outfit the personalities – and allow them to move easily, whether in the minimal dancing or walking through the aisles.

The Tower Grove Abbey’s small stage is well-suited for the show’s sparse set design, put together by Been.

For logophiles, the principal contestants are relatable. — perhaps a bit more eccentric, but these quirky characters have all learned an early invaluable life lesson: Knowledge is power.

My fellow nerds will feel at one with their tribe. For we know that summer vacation fun isn’t defined by theme park rides, water slides, and sports camps, but by summer reading lists – whether it’s for a library club, school enrichment class or a free personal pan pizza in the Pizza Hut Book It! Program.

It’s still the only musical where the cool kids are here for the orthography. Revenge of the nerds, indeed. So, Wordle can wait – and this show cannot, for there are 8 performances remaining.
