TYPES OF SYNESTHESIA IN ALPHABETICAL ORDER



Find your type here! 


This page contains an alphabetical list of synesthesia types and subtypes, some common manifestations and also a few phenomena that are similar but not considered synesthesia. The links lead to over a hundred different pages on the Synesthesia Tree where you can find out more detailed information on each type, with examples and descriptions by people who experience it.

This list is designed for searching and browsing and contains a variety of different keywords sometimes leading to the same pages, so that you can search by different terms to find what you're looking for. For a shorter, more schematic list you can visit the Site Map or the Tables, all linked on the side bar.

For more information on how the Alphabetical List works, see the end of this page.

About this Alphabetical List 

This alphabetical list includes types and subtypes of synesthesia and some of its common manifestations. There are also some phenomena that are similar but not considered to be synesthesia. 

Click on any entry to go to a page in the Tree with information on that particular type. 

The list has more than 300 entries, but they don't all lead to separate pages and it doesn't mean there are 300 types of synesthesia! They lead to just over 100 different pages. The number of types of synesthesia that exist can't be quantified with a number, for various reasons (see this page if you'd like to read about why: Why is it impossible to say how many types of synesthesia there are?).

This alphabetical list is long because it's designed for scrolling, and sometimes the terms are referenced in several different ways, to make it easier for you to find what you’re looking for because people think of and search for their experiences using different words. And also because the types of synesthesia often have more than one name. 

Remember that in the terms with a hyphen, the “inducer” or stimulus comes first, followed by the “concurrent” or secondary synesthetic perception, so for example "Taste-colour" is when tasting something makes you experience a colour, not the other way round.

If you prefer a shorter, more schematic list to find specific types of synesthesia, you can search in the Site Map (with a list of all the pages on this site, grouped by synesthesia types and key words, shorter and easy to navigate). Other pages you might prefer are the List of Synesthesia Types by Prevalence or the Table of Synesthesia Types by Combinations of Senses. If you go to the Home Page you can get an overview of all these.

Another way to quickly find what you're looking for is the Synesthesia Finder tool, where you answer brief questions and it will lead you to the page you need. It's ideal if you have experiences with crossings of the senses or other experiences that seem to fit into some category of synesthesia, but it would be difficult for you to name them.

If you're searching in this Alphabetical List (or anywhere else on the Tree site) here's a note about the spelling. Although I write in British English, I always use the word "synesthesia" in its international or USA spelling without the "a" (in British English it's spelt "synaesthesia", and both spellings are correct of course.) But I spell all other words in British English on the Tree site, so you'll find "colour" and not "color", for example. That's just personal preference!
