Hello R2D2Noble7199! :)
An anaphora is when you repeat a word or a group of words at the beginning of several sentences or phrases to create emphasis and impact.
For example, in Winston Churchill’s speech, he says: “We shall fight on the beaches, we shall fight on the landing grounds…”
By repeating “we shall fight”, he makes his message stronger and more memorable. He wants to motivate everyone to keep fighting.
I hope I'll help you! :)
Have a great day, and don’t hesitate to come back if you have more questions! :)
