Describing Scents (Resource)
I came across the following resource while googling 'how to describe smell' and it's been useful so far. I'll link it below, and I want to add additional resources for describing the other scents as I find them. If you know of any straightforward, beginner-friendly, easy to reference resources for the other senses, let me know and I'll add update my list.
- World Food and Wine, Describing Aroma. This one focuses on describing scents and aromas of food and drink, and therefore can help you describe taste as well. Be careful not to use the wordier options unless your character is a seasoned wine taster or sommelier. The synonyms the site uses to define the harder words are often more useful, such as 'an aroma that tickles the nose' for piquant.
What I use for some of my smells is also whiff.
