(S, TA.) [بطآن is an enunciative placed before its inchoative: and, being originally بَطُؤَ, it may be a simple enunciative, or an enunciative having an intensive signification; as that verb signifies simply “ it was slow,” &c., and may be used as co-ordinate to رَمُوَ, meaning “ excellent is he in his shooting! ” &c., and قَضُوَ“ excellent is he in his judging! ” &c.: or it may be equivalent to مَا أَبْطَأَ, as it is said to be in the S.
