muḍāriʿـُيَفْعُلُ·ـَيَفْعَلُmaṣdarنَعْسٌ
Core sense — he drowsed, he was heavy with sleepiness; it was soft and weakgenerated
1.1he became drowsy—يَنْعَسُ
or نَعَسَ, the latter agreeing with analogy; maṣdar نُعَاسٌ, or this is a simple noun.
[He drowsed; he was, or became, heavy with sleepiness: or he slumbered, or dozed.]
The maṣdar is synonymous with وَسَنٌ. Or نُعَاسٌ means a languor in the senses arising from the heaviness [which is the sign that comes before] of sleep; or the beginning of sleep (discussed under وسن).
he slept—يَنَامُ
According to Az, its proper meaning is وَسَنٌ, or سِنَةٌ, without sleep. Or سِنَةٌ is in the head and نُعَاسٌ is in the eye. Or سنة is the vapour of sleep which begins in the face and then passes to the heart.
[A delaying of the payment of a debt, or the like, like the drowsing, or slumbering, of the dog]—مَطْلٌ كَنُعَاسِ الكَلْبِ
That is, continual: the dog is marked by much نعاس, and is used to opening his eyes only enough for guarding, doing this time after time.
