Arabic prosody
ʿArūḍ (Arabic: اَلْعَرُوض, al-ʿarūḍ) or ʿilm al-ʿarūḍ (عِلم العَروض) is the study of poetic meters, which identifies the meter of a poem and determines whether the meter is sound or broken in lines of the poem. It is often called the Science of Poetry (Arabic: عِلْم اَلشِّعْر, ʿilm aš-šiʿr).
