Answer:
The signal words and phrases help a reader determine the text feature by giving new concept to the text. Signal words and phrases are the words that show connections between the ideas and provide effect to the text.
Step-by-step explanation:
Signal words are also known as transition words. These words help in changing the text subject.
For example:
I love drinking coffee. It keeps me awake at night.
I love drinking coffee even though it keeps me awake at night.
Here even though is the signal word which gives idea to the coffee and add transition.
These words are not related with any kind of organisation pattern and are used in the sentence to provide meaning creating new concept.
These words are able to feature the text and helps reader to determine the sentence.
There is no such evidence or thesis added to the sentence with addition of signal words.
