Final answer:
The word 'reject' comprises the prefix 're-', meaning 'back' or 'again', and the root 'ject', from the Latin 'to throw'. Thus, 'reject' means 'to throw away' or refuse to accept something.
Step-by-step explanation:
The word reject is made up of two parts: the prefix 're-' and the root 'ject'. The prefix 're-' typically means 'back' or 'again', while 'ject' comes from the Latin 'iacere', which means 'to throw'. Together, these parts give the word 'reject' the meaning of 'to throw back' which in context means to refuse to accept, consider, or submit to something, or essentially, 'to throw away' as a decision or idea.
