"Opposite Day" contains the following tropes:
- Ahem: Nocan does this to get the children's attention after WordGirl tells him how to get them to leave him alone so he can go home.
- Chekhov's Gun: The trampoline TJ struggles not to bounce on at the opposite day party comes back at the end of the episode as a make-shift replacement sail for Nocan.
- Hand Gagging: Becky does this to Scoops when his insistence on following the rules of opposite day starts causing confusion at the grocery store.
- Impact Silhouette: After Nocan breaks into the museum, it has Nocan-shaped holes in the door and one of the walls.
- Opposite Day: The premise of the episode is that Becky is holding an opposite day party. Shenanigans ensue as people have trouble differentiating when she's saying the opposite of what she means and when she's being honest, and Nocan the Contrarian gets a dose of his own medicine.
- Silent Whisper: WordGirl does this when she tells Nocan about how he can get rid of the children playing opposite day.
- Tempting Fate: At her opposite day party, Becky contently tells Bob that it's nice to relax with friends without being interrupted by some late-breaking crime report. Cue the late-breaking crime report on the radio.
- We Interrupt This Program: Parodied. The shopping music in the grocery store is interrupted for a broadcast on Nocan stealing the golden sail.
- You Have GOT to Be Kidding Me!: This is Becky's response when she hears a crime being reported right after remarking on how nice it is that there is no crime.
"Granny's Book Club" contains the following tropes:
- Affectionate Pickpocket: After capturing WordGirl, Granny May initiates a group hug with the villains so she can steal Dr. Two-Brains' wallet and the gold-plated watch they were going to give her as a retirement present.
- The Bad Guy Wins: While she does go to jail for pickpocketing, Granny May successfully accomplishes her primary goal of capturing WordGirl in order to avoid forced retirement.
- Continuity Nod: The book Granny May uses to lure WordGirl into her trap is from the Princess Triana series seen in "Princess Triana & the Ogre of Castlebum".
- Everyone Hates Fruit Cakes: On WordGirl and Captain HuggyFace's visit to Granny May, she "treats" them to fruit cake. When Captain HuggyFace tries it, he finds it too hard to bite and throws it away in disgust.
- Group Hug: All the villains hug Granny May when she brings them the captive WordGirl and Captain HuggyFace, Dr. Two-Brains even exclaiming, "Hugsies!" She takes advantage of it to steal the retirement watch she returned earlier and Dr. Two-Brains' wallet.
- I Will Show You X!: Non-comeback example. When Granny May prepares to launch into the first order of business of the villain meeting, the Butcher replies that he's "got the first order of business right here" before bringing in her retirement cake.
- Jumping Out of a Cake: The Butcher does this with the cake for Granny May's retirement party.
- Knockout Gas: Granny May uses a booby-trapped book that emanates old lady perfume with this effect to capture WordGirl and Captain HuggyFace so she can bring them to the Evil Villains Association. She tries to use it again later in the episode, only for WordGirl to use a handheld fan to blow it back in her face, defeating her.
- Noisy Shut-Up: At the start of the episode, the members of the Evil Villains Association are socialising and not paying attention to chairwoman Granny May's soft-spoken attempts to start the meeting. She finally resorts to slamming her hands down on her desk and yelling at them to "pay attention and sit down", which does the trick.
- Reluctant Retiree: The villains throw Granny May a retirement party and reveal that the Evil Villains Association rulebook states that a villain has to retire at age 75 unless they can capture WordGirl and bring her to the Association. Granny May is having none of it and sets out to do just that. Unlike in most examples of this trope, instead of the policy being cancelled she actually succeeds at this condition and keeps her "job" that way.
- Shaped Like Itself: When Chuck comes to get back Granny May's retirement watch and Granny May tells him that she knows when he's beaten, he boasts that he's "sharper than something very sharp".
- Smoking Barrel Blowout: Granny May does this with her knitting needles after encasing the Butcher in yarn at the villain meeting.
- Split-Screen Phone Call: This is used when Granny May calls WordGirl to invite her over to discuss books.
