أَصْدَقُ

[More, and most, true or veracious]. One says أَصْدَقُ مِنْ قَطَاةٍ [More veracious than a katáh]; because the bird thus called cries قَطَا قَطَا; [thus telling where it is to be found;] its name being imitative of its cry: (Meyd, and TA in article قطو:) hence it is called by the Arabs ↓ الصَّدُوقُ: the saying is a prov. (Meyd.)
