Which figure of speech is used in the line ‘where tireless striving stretches its arms towards perfection’?
The above quoted line is an example of personification. Personification is the attribution of a personal nature or human characteristics to something non-human, or the representation of an abstract quality in human form.
In the instance presented above, ‘tireless striving’ stretches its arms as if it is a human being having arms. So, human characteristics are attributed to abstract idea here.
