The Sixth Sister: An -XTH Tongue Twister

The sixth of six sisters sat six steps up packs a hard -XTH ending into a short sentence, where sixth stacks three final consonant sounds in a row.

The sixth of six sisters sat six steps up.

Sixth is a tricky word to say quickly. It ends with three consonant sounds in a row: K, S and TH. Each of them is a different move, and your mouth has to make all three before the word is over.

👅 Sounds to Practise

  • K /k/, as in sixth. The back of your tongue touches the roof of your mouth, then releases.
  • S /s/, as in sixth, sisters, sat and steps. Your tongue is close to the ridge behind your top teeth, and the air hisses through.
  • TH /θ/, as in sixth. The tongue tip comes out between your teeth at the very end.

Quick test: say six and then sixth. Sixth adds a TH after the S. That small extra sound is the difficult part.

🐢 Start Slow

Say each chunk slowly.

The sixth of six
sisters sat
six steps up.

🚶 Normal Speed

Say it at a natural pace, with the stressed syllables in capitals:

The SIXTH of SIX SISters SAT SIX STEPS UP.

🚀 Tongue-Twister Mode

Say it three times in a row, as fast as you can:

The sixth of six sisters sat six steps up.

If you drop the TH or the K, slow down and finish the word fully. Each sound should be clear.

🤯 Why Is This So Difficult?

Look at the end of each word:

sixth / six / sisters / sat / steps

  • Sixth has K, S and TH at the end. Three consonants at the end of one word is unusual, so your mouth is not used to it.
  • Sixth and six sit close together in the sixth of six. Your mouth has to go from K-S-TH to K-S, and then straight on to sisters, which starts with S.
  • Sisters, sat and steps all start with S. Your tongue keeps going back to the same place, and it is easy to run them together.

👀 Words to Notice

These pairs show how the ending changes the word:

  • six / sixth: the same start, with an extra TH at the end
  • five / fifth: the V becomes F, and a TH is added at the end
  • twelve / twelfth: the ending changes from V to F, with a TH added

🏆 OddLingo Challenge

  1. Round 1: say it slowly, one chunk at a time, with no mistakes.
  2. Round 2: say the whole sentence once at normal speed.
  3. Round 3: say it three times fast without stopping.

Bonus round: if you survived all three, try this one:

The sixth sheep sipped six sweet sodas.

🧐 Did You Know?

Numbers in English often change their ending when they become an order. Six becomes sixth, five becomes fifth and twelve becomes twelfth. The -TH ending is how English turns most numbers into an order. The first three are irregular: first, second and third.
