WASHINGTON - Two Canadian schoolgirls have advanced to the semifinals of the famous Scripps National Spelling Bee.

Twelve-year-olds Jennifer Mong of St. John's, N.L. and Mignon Tsai of Abbotsford, B.C., are among 50 competitors to go on to the semifinals following two days of tense competition.

Zhongtian Wang, 11, of Windsor, Ont., was eliminated.

In Round 2 of the spelling bee on Wednesday, Mong spelled "limousine" correctly, Tsai aced "hyacinth" but Wang got a tough one — "issei," a word for a Japanese immigrant. The audience applauded in relief when she nailed it.

In Round 3, Tsai got a difficult word: "leegte." Mong got "vaticination" right and Wang spelled "embarcadero" correctly, but her scores from a 50-word computer quiz on Tuesday didn't give her enough points to take her to the semifinal.

The 50 remaining spellers, whittled down from a field of 278, square off in the semifinal on Thursday morning at a glittering conference centre in National Harbor, Md., just down the Potomac River from the U.S. capital.

If they get past that round, they'll compete Thursday night in the final, to be aired live on ESPN.

Mong and Tsai are competing a year after Canadian Laura Newcombe took second place at the world-renowned contest.

Newcombe, now 13, came tantalizingly close to winning the contest last year in a nail-biter of a final round. The Torontonian was tripped up by the Greek word "sorites."

Canadians have been a strong presence at the Scripps competition for years, and have had several close calls. Nate Gartke and Finola Hackett of Alberta were previous runners-up.

This year's competition includes schoolkids not just from the U.S. and Canada, but from the Bahamas, China, Ghana, Jamaica, Japan, New Zealand and South Korea. They're all on hand to spell out words that get progressively more difficult as the contest proceeds.

The 2012 contest also featured its youngest-ever speller — six-year-old Lori Anne Madison from Woodbridge, Va.

The girl spelled her first word correctly on Wednesday — "dirigible" — but flubbed her second word, "ingluvies," and was eliminated from competition.

Most spellers at the bee are between the ages of 12 and 14 years old.

  • Zooey Deschanel

    Shockingly, it's not the last name that gets us with this "New Girl" star -- maybe years of writing about her "Bones" star sister Emily have helped -- but the double-"o" in Zooey just loses us sometimes.

  • Matt Czuchry

    This "Good Wife" star's last name is pronounced "zoo-kree." Can we just spell it that way, too?

  • Kristin Chenoweth

    "GCB" might be canceled, but our mantra of "Kristin with an 'i,' Chenoweth with an 'e'" will never go away.

  • Zach Galifianakis

    We loved "Bored to Death" and are hoping for more "Between Two Ferns" TV specials ... just to get that name right.

  • Gabourey Sidibe

    "The Big C" star has a seriously confusing name spelling.

  • Matthew McConaughey

    He's coming to TV! So guess we better start remembering that it's only one "n."

  • Famke Janssen

    This "Nip/Tuck" lady's name is as exotic as her looks.

  • Alexander Skarsgard

    Not to be confused with movie man Peter Sarsgaard, this "True Blood" hottie is worth the extra effort.

  • Kristen Wiig

    Doesn't Wiig always look like it's missing a consonant? It's not, but Kristen got plenty of them with her former "SNL" gig.

  • Christina Aguilera

    "The Voice" coach leaves us speechless fairly often ... but her name stumps us every time.

  • Bruno Tonioli

    On a difficulty scale of 1-10, Bruno's last name ranks on the tougher side. Just like his "Dancing With the Stars" judging.

  • Mary Steenburgen

    This "30 Rock" guest star spells it exactly like it sounds ... even if we doubt ourselves every time.

  • James Van Der Beek

    "Don't Trust the B---- In Apt. 23" lets Van Der Beek spoof himself -- now we're ready for him to target his fellow Hollywood "Van" clan. Like ...

  • Lisa Vanderpump

    This "Real Housewives of Beverly Hills" beauty isn't one for excess capitalization or spaces -- it's all one word, all fabulous.

  • Laura Vandervoort

    This "Smallville" and "V" alum is stunning, as is her last name. (Try saying that three times fast!)

  • Emily VanCamp

    We don't want to know what this "Revenge" star would do if we forgot her capital "C" or left her "Van" hanging.

  • Kyle MacLachlan

    "Portlandia" has the proud honor of having MacLachlan guest star ... and making sure they remember all those "a"s.

  • Mariska Hargitay

    We love watching people butcher Mariska's name when she collects all her awards for "Law & Order: SVU." We're guessing it doesn't thrill her, though.

  • Maksim Chmerkovskiy

    Are all Ukranian names this tricky? Also, did Maks have to bring his brother to "Dancing With the Stars" too? Now it's Chmerkovskiy x2.

  • Julianna Margulies

    Both of these names somehow stump us, and judging by a lot of comments from "Good Wife" fans, we know we're not alone.

  • Steve Carell

    "Office" alum Carell and movie star Will Ferrell always make our brains hurt -- we may never get it right without Googling.

  • Ali Fedotowsky

    We'd be fine going back to the days when the "Bachelors" and "Bachelorettes" were all just one-name wonders. Please?

  • Madchen Amick

    There's an umlaut over the "a" in Madchen -- we think -- and umlaut's get us every time.

  • Adewale Akinnuoye-Agbaje

    This "Lost" alum's name still leaves us scratching our heads, much like the show itself.

  • Courteney Cox

    Cox has worked hard enough to deserve that extra "e" in Courteney (but it still bugs us).

  • Jason Segel

    One of "How I Met Your Mother's" biggest twists? That Jason Segel's name is always the hardest to spell! (Cobie Smulders thanks you, Jason.)

  • Yunjin Kim

    We adore this "Lost" alum, but we're already trying to train ourselves to spell her name correctly before she returns to ABC with "Mistresses."

  • Damian Lewis

    This man's "Homeland" is England, and that's probably why we always assume his first name is more complicated than it is. Damien or Damian? It always takes a second look.

  • Britney Spears

    It's Britney, b-tch! Now that this diva's on "X Factor," we're banning all urges to "Brittany" her.

  • David Boreanaz

    This "Bones" star's last name really is spelled just like it sounds ... sometimes the easiest ones are the hardest.

  • Madeleine Stowe

    "Revenge" is a dish best served cold, and spelling this star's name gives us a chill of uncertainty every time.

  • Sigourney Weaver

    This summer's "Political Animals" has us boning up on White House policy and this star's tricky first name.

  • Milo Ventimiglia

    This "Heroes" alum's last name is a mouthful ... and, if we're being honest, we're still not totally confident in our pronunciation of it either.

  • Megalyn Echikunwoke

    This lovely lady was pulling double-duty on "House of Lies" and "90210," which meant double the IMDb spell-checking.

  • Marg Helgenberger

    This "CSI" alum's name still stumps us -- anyone else feel an overwhelming need to drop the "er" when saying or spelling her last name?
