Qalqalah Sughra refers to a specific phonetic rule in Arabic pronunciation, particularly concerning the articulation of certain consonants. It applies to the letters ب (b), ج (j), د (d), ق (q), and ط (t). When these letters appear with a vowel sound, they are pronounced with a slight echo or bounce, creating a distinct sound that enhances the clarity of speech. This rule is part of a broader concept known as Qalqalah, which includes both Qalqalah Sughra and Qalqalah Kubra. The latter involves a stronger echo effect and is applied when these letters occur at the end of a word. Understanding Qalqalah Sughra is essential for proper Arabic pronunciation and fluency.
