Learning the Quran at home – Lesson 6: The shadda (doubled letters)

A small sign like a “w” above the letter: in the sixth lesson you learn the shadda (Turkish: şedde) and read syllables and words such as thumma, inna and rabbi.

One letter, read twice

The shadda (Turkish: şedde) is a small sign that looks like a “w”: ـّ . When it stands above a letter, that letter is read twice – once without a vowel (as with sukun) at the end of the previous syllable, and once with its vowel at the start of the next.

How it works

So رَبِّ is read as رَبْ + بِ – “rab-bi”. The shadda almost always carries a vowel sign as well: fatḥa and ḍamma are written above the shadda, kasra below the letter (in some editions directly below the shadda). Pronounce the doubled letter clearly and a little longer.

Practice: syllables with shadda

The Elif-Ba exercise with shadda – in brackets the reading in the Turkish Elif-Ba:

اَبَّab-ba (eb-be)
اِبِّib-bi (ib-bi)
اُبُّub-bu (üb-bü)
اَتَّat-ta (et-te)
اِتِّit-ti (it-ti)
اُتُّut-tu (üt-tü)
اَقَّaq-qa (ak-ka)
اِقِّiq-qi (ık-kı)
اُقُّuq-qu (uk-ku)

Practice: words with shadda

Read each word and listen for the doubled letter:

ثُمَّthum-ma (süm-me): then
إِنَّin-na (in-ne): truly
كُلُّkul-lu (kül-lü): every, all
عَلَّمَʿal-la-ma (al-le-me): he taught
رَبِّrab-bi (rab-bi): (of the) Lord

عَلَّمَ appears in the first revelation (Surah 96, verse 4), رَبِّ in the second verse of al-Fātiḥa. In the word Allah (اللّٰه), too, the Lam carries a shadda – more on that in Lesson 10.

Next steps

Practise the syllables with shadda until you can clearly hear the difference between a single and a doubled letter – ideally have our imam say them for you. In Lesson 7 you will learn the tanwin: the double vowel signs at the end of a word.
