Al-idghaam al-sagheer has three categories, these are This common idghaam has two branches: kabeer (large) and sagheer (small).Īl-Idghaam Al-kabeer: occurs when a voweled letter precedes another voweled letter such that they become one letter with a shaddah on it.Īl-Idghaam Al-sagheer: occurs when a saakin letter precedes a voweled letter, such that they become one letter with a shaddah on it. Idghaam Al- ‘aam: the common/general idghaam is to sound the first of two letters as the second – sounding the two letters as one letter with a shaddah on it. Similarly, it’s easier for the tongue to merge two letters, and sound out the one with the more dominant characteristic. We do this when we categorise objects with similar characteristics (using the dominant characteristic as the go-to label) because it’s easier for us in the end to pull out what we need. Merging two similar things is something we do all the time.
