زَيْدٌ أَسَدٌ
Zayd is a lion: he is depicted as possessing lion-like courage.
Neither an overt likeness particle nor the qualifier “in courage” is present. The subject is presented directly in the lion's image, and the resemblance is not verbally limited to one feature. Both leading means of intensification therefore converge.
This is a standard form for explaining an eloquent simile, while the final interpretation of an actual utterance still depends on its setting. The subsequent discussion of figurative language treats the distinct question of how a word is being used.
