It is more often the case that many writers are not able to write everything down to express what they have to convey to the reader. It is not possible to do so.
The full meaning of what has been written can be found by looking beyond the meanings of the written words and sentences in an excerpt, which means that the meaning can be known by inferring, interpreting or identifying what has been implied.
This can be done from two types of sources that can be found in the text itself such as:
a. The meaning of the words or sentences used. What do the words mean? What did the sentences say?
b. The circumstances or situations that the sentences convey to the reader. Where the event is taking place, is someone in difficulties, happy, lost or sad? Is there doubt, conflict, anger, joy and happiness. Is the situation festive or somber and so on.
The physical and social environment settings in which the sentences are written can also provide meanings that are beyond the scope of words and sentences to convey.
What is written in a text provides the reader with knowledge but what is not written but also very much part of he text provides experience for the reader. One might say that the written word is the text's form while the unwritten word is the soul of the text which the reader must look for and find. It is a hidden experience.
She walked to his house in the rain. She was drenched and very cold. It was obvious to him she needed a dry dress and somewhere to warm herself. I had no warm clothes for her but I gave her hot tea.
When someone reads the text, it would be very simple to understand everything that has been written. Nevertheless, some details have been left out of the text which means that the sentences in the paragraph do not have information to answer the following questions:
1. Why was she wet?
2. What had made her cold?
3. Would the cup of hot tea warm her up?
4. Did she require another form of warmth?
6. Who was she?
7. Where did she come from?
There is no doubt that the answers to these questions would become part of the text itself. They are the hidden pieces, the implied details that we have to look for to get at the very soul of the text.
