  Semantic reism is parallel to the ontological aspect of this doctrine. The key idea consists in the distinction of genuine names and apparent names (onomatoids). A name is genuine if and only if refers to things, that is, to concrete physical things. By contrast, onomatoids are words that allegedly refer to abstract entities, “allegedly” because their referents do not exist. At first glance, apparent names are similar to empty terms. However, this resemblance is merely apparent, because empty nouns are genuine names and can always be decomposed into non-empty genuine names (e.g., “round square”). This becomes evident when we try to formulate the conditions of meaningfulness for sentences. In general, a sentence is meaningful if and only if it consists (except for logical constants) only of genuine names or is reducible to such sentences. For example, the sentence “all cats are animals” is reistically meaningful, but “properties are abstract objects” is not. Furthermore, “a square triangle is rectangular” is good, but “sets exist outside of time and space” is not. The sentence “whiteness is a property of snow” can be reduced to “snow is white”. This example shows how to translate some sentences with apparent names into purely reistic statements.
