A little curiosity goes a long way.

Fox

In the Arabic word ثَعْلَب (“fox”), the first letter is thaa. Count the three dots above its first letter.

One letter. Four shapes.

The final thaa joins to the preceding ḥaa on its right.

The name stays thaa in every shape. A connected form does not add a new sound. Gold highlights this letter in each example.

1Three short vowelsA little mark changes the sound.

The letter’s name is thaa. Follow the Arabic tiles from right to left.

Listen to the whole word.

Finish with th, without adding a vowel after it. Thaa allows air to continue: sukūn removes the vowel, rather than requiring an abrupt stop to the breath.

4Two letters, one written shapeShaddah · three vowel sounds.

A shaddah joins two of the same consonant. The first has sukūn; the second has the vowel. Read each Arabic sequence from right to left.

Hold the doubled consonant, then continue into its vowel. Do not insert a vowel between the two consonants.
5One word, three tanwīn endingsSee the ending in a real word.

Compare three full endings on the same noun. The doubled vowel mark adds an n sound when the ending is pronounced in full.

At a pause, bāḥithun and bāḥithin become bāḥith; bāḥithan becomes bāḥithā. Choosing the ending in a sentence comes later.
