In Greek, there are two forms of the negative adverb “not”: one for indicative verbs (e.g. He is not teaching.) and one for imperative verbs (e.g. Do not teach.) The negative adverb is placed immediately before the verb.
The following table shows the two negative adverbs, along with the verb παιδεύω in indicative and imperative forms:
| Adverb | Mood | Example | Translation |
| οὐ | Indicative | οὐ παιδεύει | He isn’t teaching. |
| μή | Imperative | μὴ παίδευε | Don’t teach! |
