However, depending on the context, other translations might be more appropriate. Here are some alternatives:
* சுயவிருப்பத்தின் (suyaviruppaththin) - This emphasizes the personal choice involved.
* தன்னிச்சையான (thannicchaiyaana) - This emphasizes the freedom of action.
* விருப்பத்தின்படி (viruppaththinpadi) - This translates to "according to one's wish".
* சந்தர்ப்போசிதமான (sandarppōsithamāṇa) - This implies that the decision is based on the circumstances.
The best translation will depend on the specific context in which you are using the word "discretionary."
