There is no standard suffix that makes a word an abstract noun. An abstract noun is determined by the meaning of the noun or the use of the noun.
An abstract noun is a word for things that your five senses cannot detect. You can't see them, hear them, smell them, taste them, or touch them. They are words for things that you know, learn, think, understand, or feel emotionally.
