الكلام الفصيح هو كالعسل في الحلاوة
Eloquent speech is like honey in sweetness.
“Sweetness” brings the experience of effective speech close to the listener. Yet the gustatory sweetness of honey and the pleasant effect of eloquent speech are not literally the same sensory property. The relation lies in agreeableness or delight, with sweetness serving as a convenient indication.
A subtle point is that speakers may mention an associated consequence of the common respect rather than the most exact abstract description of the resemblance. One should not insist that the literal physical meaning of every word must apply identically to both sides.
