What is the Antonym for depleted? [closed]

I have searched every online dictionary and can not find a word which means, not depleted."Undepleted" is apparently not a word. I want to say

"His funds remain not depleted by unnecessary expenses"

but "not depleted" and "remain full" doesn't cut it for me. Any ideas?

Either "replete" or archaic (as used in Dracula) "eked out"

Firstly, undepleted is an established word as pointed out by a couple of users in comments.

However, if you are looking for alternative words, you can consider unaltered

Unaltered (adj.)

not altered, changed, or modified

[Dictionary.com]

In your case,

His funds remain unaltered, even with all his unnecessary expenditures

Regarding undepleted, I could indeed not find it in either the Cambridge dictionary, nor the Merriam-Webster. So, you could argue the word 'does not exist', but as FumbleFingers and Rathony pointed out in the comments, the word is in general use and has been defined in other dictionaries. I would thus argue undepleted is an actual word.

Now, while I am not a native speaker, I personally feel that undepleted implies a process of depletion, e.g. at the current rate of spending, depletion is guaranteed to happen sometime in the future, but has not happened yet.

If this is what you are trying to convey, then yes, undepleted would be a antonym. If you however desire to convey that his funds remain the same since they are not affected by any spending, I would advise BiscuitBoy's answer of unaltered.

Finally, since there has been some confusion in the comments regarding the actual spending, maybe you should rephrase to make clear that either he is not spending unnecessarily (use unaltered), or spending too lavishly (use undepleted).
