I'm trying to understand the distinct difference between these terms, they seem very similar but there is a different pattern behind them. Could you tell me with example how do you differentiate between them?
Like all terms in philosophy, these have different senses in different contexts and between different philosophers. I think actually the common contrasts are between singular and general and between universal and individual or particular.
A singular term is one that refers to just one object : e.g. 'the Great Pyramid', 'the Eiffel Tower', 'the tallest person in the world'. A general term by contrast applies in principle to any number of objects : e.g. 'planet', 'star', 'dog'.
A universal is a property, attribute or feature that is possessed by all members of a collection or set. Thus redness is a property possessed by all red objects. A particular or individual is an example or instantiation of (to keep to the example) redness - this patch of red two inches to your left.
'Individual' is a particularly tricky word, however - not that any of them are quite straightforward. An individual can be a particular as above but it can also be something which is indivisible at some level or under some description.
Just ask if you need further clarification.
