Μή versus οὐ in conditional clauses

Greetings all,

I finally have some time to get back into Greek again!

I’m supposed to translate the sentence “I would be sorry if you were not to persist with Greek.”
My attempt is:
λυποίμην ἄν, εἰ μὴ?οὐκ? ἐπιμένοις τῇ Ἑλληνικῇ.

I asked ChatGPT5 what the correct negation is, and it gave me this answer, which strikes me as too simple:

This is a core rule of Ancient Greek negation, and your question goes straight to the heart of how Greek mood works.


Short answer

Because the verb is in the optative mood, and:

μή negates non-indicative moods
οὐ negates the indicative

Since ἐπιμένοις is optative, it must be negated by μή, not οὐ(κ).


The rule (clean and absolute)

Mood / construction Negation
Indicative οὐ(κ)
Optative μή
Subjunctive μή
Imperative μή
Infinitive μή
Participle (usually) μή

So:

  • οὐ = factual denial (“it is not the case that…”)

  • μή = potential, feared, intended, hypothetical, or willed non-reality

Is that really the rule?

No that’s bad, very bad. All conditional clauses are negatived with μή. Potential clauses such as “I would be sorry” have optative + ἄν, negative οὐ.

Okay, thanks, Michael. So is my translation okay?:
“I would be sorry if you were not to persist with Greek.” = “λυποίμην ἄν, εἰ μὴ ἐπιμένοις τῇ Ἑλληνικῇ.” Is ἐπιμένοις + dative correct? Would “διατελοῖς τῇ Ἑλληνικῇ**”** be better?

Always turn on “thinking” mode for grammar questions, especially for Ancient Greek and Latin. I only have a work ChatGPT account at the moment, but here is Gemini in thinking mode on what I think you asked.

Great answer, thanks! What an improvement over a reference to a section of Smyth or the Cambridge grammar (neither of which I have). ChatGPT5 doesn’t have thinking mode but your answer was so impressive maybe I’ll switch to Gemini, at least for Greek grammar questions.

ChatGPT5 doesn’t have thinking mode

Click the “+” on the left side of your prompt.

I’m using ChatGPT5.2. If I remember correctly you are using a more advanced version with ”m” in the name. When I click on the plus sign, “thinking mode” isn’t on the menu (although there’s an “agent mode”). When I asked it if it has a thinking mode, it gave a long answer beginning like this:
Do you have a thinking mode?

Short answer: yes — but not in the way people sometimes imagine.

Here’s the clear, policy-safe explanation.


How my “thinking” works

I do reason internally when answering questions:

  • I analyze context

  • weigh interpretations

  • connect facts

  • choose wording carefully

That internal reasoning is not shown step by step unless it’s helpful and appropriate (e.g. in math or logic explanations).

So:

  • :check_mark: I do think

  • :cross_mark: I don’t expose raw internal chain-of-thought by default


What you can ask for instead (and get)

You can always ask me to:

  • explain my reasoning in a clear, structured way

  • compare interpretations

  • justify a conclusion

  • walk through an argument step by step (cleanly, not verbatim internal notes)

That’s different from dumping internal scratch work, but functionally gives you the insight you care about.

For example:

  • “Why does interpretation A fit better than B?”

  • “Can you unpack the logic behind that?”

  • “What assumptions are doing the work here?”

Those are all fair game.


It’s talking about something else and you have pasted its confused output to a discussion thread. Click this plus button:

And then click where it says “Thinking”

I clicked on + the first time and it doesn’t show the same menu:

It specifically says it doesn’t have anything called “thinking mode” and there’s no hyperlink “Thinking” in my version. I clicked on + the first time and it doesn’t show the same menu (see popup menu below).

:

I’ll have to check at work, where I have access to various things. I let my personal subscription to ChatGPT expire in December.

Some Google searching suggests that it’s in this menu with 5.2.

However, it may be feature-locked in whatever you are subscribing to.

It specifically says it doesn’t have anything called “thinking mode” and there’s no hyperlink “Thinking” in my version. I clicked on + the first time and it doesn’t show the same menu (see popup menu below).

:

That’s the Pro version, which I don’t have. Judging by the descrription “Thinking: Thinks longer for better answers” it probably corresponds to “Deep Research” in my popup menu.

Deep research is something else again. Also, ChatGPT knows very little about its own features in Instant mode (mostly due to training cutoffs?). It thought you were asking about self-awareness in the above, and was giving you a version of the canned spiel.

Gemini is great! Thanks for mentioning it. I just asked “How to decline μηνις” and Gemini (show thinking) came up not just with the declension but detailed grammatical notes and contextual usage, tips for starting “Pharr”, etc. etc. I’m most impressed.

“Show thinking” is good, and I always leave it on, but confusingly, “Thinking” mode is different again. For Gemini, click here where it says “Fast”

And choose Thinking

Note: I found today that Claude’s newest Opus 4.5 was very confused by Smyth’s formatting when I asked it to implement some accentuation rules in code. Apparently Smyth 70ff, with the sentences broken by big bold section numbers, is a bit confusing for it. Maybe not an issue if you cite the Cambridge Grammar?

Thanks. “Show thinking” seems to be the default setting. Will try “Fast” next time.

“Show thinking” is completely separate from modes like “Fast” and “Thinking”. “Show thinking” just means that you get the self-reflection content in your browser. In “Fast” mode, not much reflection goes on, it’s just zippy answers. In “Thinking” mode, it goes slowly and more carefully and is far more compute-intensive on the service provider side (more expensive).

Yes you have the construction, and εἰ μὴ ἐπιμένοις τῇ Ἑλληνικῇ would do, but διατελοῖς (correct -οῖς to οιης!) better, e.g. ei mh diateloihs thn ellhnikhn askwn. (Forgive temporary absence of Greek font on new computer!)

Okay, thanks a lot Michael!
