You can get the definition(s) of a word in the list below by tapping the question-mark icon next to it. The words at the top of the list are the ones most associated with sour, and as you go down the relatedness becomes more slight. By default, the words are sorted by relevance/relatedness, but you can also get the most common sour terms by using the menu below, and there's also the option to sort the words alphabetically so you can get sour words starting with a particular letter. You can also filter the word list so it only shows words that are also related to another word of your choosing.

There are already a bunch of websites on the net that help you find synonyms for various words, but only a handful that help you find related, or even loosely associated words. So although you might see some synonyms of sour in the list below, many of the words below will have other relationships with sour - you could see a word with the exact opposite meaning in the word list, for example. So it's the sort of list that would be useful for helping you build a sour vocabulary list, or just a general sour word list for whatever purpose, but it's not necessarily going to be useful if you're looking for words that mean the same thing as sour (though it still might be handy for that).
If you're looking for names related to sour (e.g. business names, or pet names), this page might help you come up with ideas.
