طَعْنَةٌ سُلْكَى

[A thrust, or piercing thrust,] directed right towards the face. (S, K.) And أَرٌ سُلْكَى [An affair] rightly directed; (K, TA;) and so رَأْىٌ [an opinion]: (TA:) or the former, [an affair] following one uniform course. (ISk, TA.)

In the saying of Keys Ibn-'Eyzárah,

غَدَاةَ تَنَادَوْا ثُمَّ قَامُوا فَأَجْمَعُوا

بِقَتْلِىَ سُلْكَى لَيْسَ فِيهَا تَنَازُعُ

he means [In the morning when they congregated, then arose and determined upon my slaughter] with a strong resolution in respect of which there was no contention. (TA.)
