Core sense — an intervening space between two things; a hollow where water collects; wide; stillgenerated
1.1
Also: an intervening space between two things, as, for instance, between the two humps of a camel of the kind called فَالِج.
1.2
A place where water remains and collects or stagnates.
A 'Obeyd: a جَوْبَة [that is, a depressed place, or a hollow, or an excavation, or one that is round and wide] in the place of abode of a people, into which the rain-water or other fluid flows.
Or, like رَهْوَةٌ, a depressed place in which water collects; and both words also mean an elevated place, so that they have two opposite meanings.
Or رَهْوَةٌ means an elevation like a hillock, on a hard and high, or high and level, tract of ground, or on a mountain, where hawks and eagles alight.
Or a hillock tending to softness, two or three cubits high, but only in a soft tract of ground, or in hard, or hard and level, ground of earth, mould, or clay, not on a mountain.
Some hold that it means a mountain itself; for Ghaṭafān are called in a tradition رَهْوَةٌ تَنْبَعُ مَآءً, meaning a mountain welling forth water; or the phrase means that in them were roughness and hardness.
The plural [apparently of رَهْوٌ, and by another account of رَهْوَةٌ, each agreeable with analogy] is رِهَآءٌ.
1.3
[Also, according to Golius, on the authority of the KL: a way through a market-place, at the sides of which the sellers sit; but it is not in my copy of the KL.]
2
Also: wide, ample, or spacious.
2.1
A well wide in the mouth.
2.2
A woman wide in the vulva; also رَهْوَى and رَهَآءٌ.
Or a woman who will not refrain from wrongful conduct, or adultery, or fornication; also رَهْوَى.
Or a woman who is not approved on the occasion of جِمَاع, because of her being wide.
2.3
A thing dispersed, or scattered.
2.4
And sometimes: quick, or swift.
2.5
And: still, quiet, or motionless.
2.6
And [hence, or مَطَرٌ رَهْوٌ]: a still rain.
3a company of horsemen making a raid, or incursion, following one another—غَارَةٌ رَهْوٌ
the people are ranged consecutively, facing one another—النَّاسُ رَهْوٌ وَاحِدٌ مَا بَيْنَ كَذَا وَ كَذَا
Also: a company of men following one another.
That is, مُتَنَاظِرُونَ [apparently meaning that the people are disposed consecutively in one double rank, partly one sort and partly another, facing one another].
4
Also: a certain species of bird; as some say, the [species of crane called] كُرْكِىّ; or a certain water bird resembling the كركىّ. Plural رِهَآءٌ.
5
And: a head-covering which is next to the head, and which very soon becomes dirty.
