When it comes to describing a feeling of being hopelessly in love with someone or something, there are many synonyms to use in place of "world was smitten." Some options include "head over heels," "spellbound," "infatuated," "enchanted," "captivated," "mesmerized," and "besotted." Each of these words carries its own nuances and shades of meaning, but they all speak to the intense, all-consuming nature of the emotions involved. Whether you're talking about a person, a passion project, or a place, any of these descriptors can help capture the sense of being completely swept away by something.
