A simile may gather several sensory traits such as colour, flavour, smell, motion, or sound. Several traits do not automatically produce several independent similes: they may jointly constitute one likeness.
Conceptual traits can also combine. A person compared with the sun may be likened in eminence, visibility, or general benefit, not merely light. Yet the intended trait must be established by context; every conceivable similarity is not necessarily relevant.
Thus multiple aspects in one likeness differ from several separate comparisons.
