| Index words: index words are words like “here”, “there”, “now”, “me”, etc. which require a closer determination, so that a sentence which includes them can be determined whether it is true or false. A sentence with index words is therefore context-dependent. Index words are not demonstratives. See also deixis, anaphora, context dependency, indexicality._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Charles Sanders Peirce on Index Words - Dictionary of Arguments
Berka I 29 Index/indicator/Peirce: E.g. pointing finger - the physical evidence: does not say anything, it just says "there!" >Indexicality, >Ostension, >Pointing, >Ostensive definition. Berka I 30 Conclusion/Peirce: needs in addition to symbol (for truth) and index (both together (for sentence formation) the 3rd character: the icon: because inference consists in the observation that where certain relations exist, some other relations can be found. >Conclusion, >Symbols, >Icons, >Relations. These relations must be represented by an icon - e.g. the middle term of the syllogism must actually occur in both premises.(1) >Syllogisms, >Premises. Berka I 31 E.g. the empty spaces that must be filled with the symbols (x, y, ...) are indices of symbols.(1) >Variables, >Constants, Individual variables, >Individual constants, >Logical operations, >Logical formulas. 1.
