We've discovered that generally if a decision must be made "tuj" deciding not to spend money is usually the best one.
Why does "decidu" end in "u?" I thought all verbs end in "-as," "-i," "-is," or "-os"
The ending -U is called the volitive mood. It refers to commands, wishes, desires, etc. Its closest English equivalent is the imperative, or command, mood; but it covers much more ground.
There are some questions in the time section that need the imperative section to answer which is on the same tier.
Tuj = Immediately, even sooner than that, ASAP, and step on it!. (why are you still here?)
Nun = now, currently, in the present moment. (just wait a bit, please)
