When describing the smell of something, using the same phrase repeatedly can become tiresome. Luckily, there are plenty of synonyms for "smelt of" that can be used to add variety to your descriptions. One option is "reeked of," which can convey a strong and unpleasant odor. "Wafted with" implies a more delicate scent carried on the air, while "emanated" suggests that the smell is coming from a specific source. "Permeated" is a good choice when describing a pervasive smell that seems to saturate everything around it. Finally, "reeked" is a more informal option that can be used for more casual writing.
