A text can be inconsistent in or for a given situation if its author cannot infer a meaning or a idea through the articulation of its sentences and paragraphs and through linguistic resources (score, vocabulary, etc.).
Textual coherence is the logical relationship between ideas, as these must complement each other, it is the result of the non-contradiction between parts of the text.
The coherence of a text includes factors such as the producer and receiver's knowledge of the subject covered in the text, knowledge of the world, the knowledge they have of the language they use and intertextuality.
It can be concluded that a coherent text is one from which it is possible to establish meaning; is understood as a principle of interpretability.
Take the example: "Children are starving because of the country's wealth."
"I love sandwiches because it makes me fat."
The sentences above are contradictory, do not present clear information, therefore, they are inconsistent.
