The task is to identify the word that does not belong with the others based on their meanings.
Let's analyze the options:
- Temporal: related to worldly as opposed to spiritual affairs; secular. Additionally, it implies something temporary or fleeting in duration.
- Ephemeral: lasting for a very short time.
- Transient: lasting only for a short time; impermanent.
- Eternal: lasting or existing forever; without end or beginning.
Upon examining these words, we notice that:
- Temporal, ephemeral, and transient all suggest brief or temporary existence.
- Eternal indicates something that lasts forever, which is the opposite of the other options.
Therefore, the odd one out is eternal as it does not imply a temporary state like the others.
