You should use techniques to back up your argument! Then by having an example this will give further proof of your point.
for example:
Coleridge is able to transport his readers on the imaginative journey by actively engaging them through the use of first person narrative and the conversational tone, “Well, they are gone, and here I must remain.” This first line is an example of the colloquial language of the conversation poem, commencing with “well” and the first person address through “here I must”. The punctuation is used by the poet to express feelings such as frustration “this lime tree bower my prison!”
Hope that helps! The answer is yes you need examples.
