|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. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |

Index/Semantics/Grammar/Lewis: Indices are packages of everything except meaning that enter into the determination of extensions.
Index/Context/Truth conditions/Lewis: Contexts cannot replace Indices (place, time, world, speakers), because it may be that we need to move time and worlds to find out the truth value of sentences - the shortest: context as the first coordinate, the others movable - then a) original index with movable properties - b) shifted indices.
Schwarz I 206
Index coordinates/Lewis: E.g. for operators like "strictly speaking", "anywhere": full semantic value: function of situations, times, worlds, places and precision standards on truth value. - Equivalent: Assigning functions of times, worlds, places and precision standards on truth value to situations: the latter is often called proposition, or actual semantic value: (Montague, Cresswell, Kaplan, Stalnaker): here the semantic value varies from situation to situation, from context to context - Schwarz: Dichotomy of the possibility space - (s) always t/f)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
