وَجَّاسٌ

ذُو مِرَّةٍ بِدِوَارِ الصَّيْدِ وَجَّاسُ

[An intelligent person, acquainted with the circumvention of game: see دَاوَرَهُ]: (M, article دور:) (ISd holds it to be a possessive epithet, since it has no known verb [of a suitable meaning that is unaugmented]: or [the meaning of these words is, a person possessing skill in circumventing game, a listener, or attentive, to their sounds and motions; for], according to Es-Sukkaree, رجّاس means يَتَوَجَّسُ.
