Peirce made the difference between Sign, object and interpretant, where:
Sign: It is something which stands to somebody for something in some respect or capacity. Also, it is a union of the thing denoted and the mind.
Object: It gives characteristics (describes) of something in order to identify the sign. It is describable in terms of its effects.
Interpretant: "proper significate effect” of the original sign. Also, it is produced in the mind of each person.
Peirce also proposed:
Icon: Resemble or imitate something.
Index: Physically connected, show something about things.
Symbol: Context, meaning by usage.
And he proposed a list of categories:
-Firsteness or feeling: Prereflexive; there is no analysis, reference, comparison nor process here. It is atemporal. The places with esthetic connection are usually where firsts may be found.
-Secondness: Actual existence, reality. In contrast to the firstness, there is reflection here. Other recognized as other. It is unique.
-Thirdness: Relationship between events, the person mediates here.
Later he exposed 'Branches of semiotics':
-Grammatical speculative: Find out (discover) what must be true of the sign in order that they may embody meaning. A word has a meaning as we can communicate our knowledge to others and getting others communicated knowledge, what grammatical speculative does is to allow that communication- ground.
-Logic proper: Formal science of the truth of representations- object
-Pure rhetoric: One sign gives birth to another- One thought brings forth another.
