Definition: A reserve or substitute.
Alright class, settle down and let’s take a look,
At this word “backup,” a little bit of hook!
The dictionary tells us, it’s true you see,
“A reserve or substitute” – that's the key!
Think of it like this, a lovely little rhyme,
If something goes wrong, it’s there in good time.
Like having a backup plan, when things don't go as planned,
Or saving your files, across the digital land!
It means an extra copy, safe and sound you know,
Just in case the original starts to slow.
So “backup” isn’t just one thing, it’s a safeguard bright,
A second chance, shining with all its light!
Does that make sense? Any questions for me?
