Verb moods: Imperative, Infinitive and Coniunctive

Verb have a number of moods, including the indicative, imperative, infinitive and coniunctive. I will go through these four here.

Indicative

No specific affix.

Is used to state actions in the present, past or future. Also used to describe habits.

Imperative

-εтι for singular and dual;
-εтε for plural;
-υcтε for general advise

Is used to give orders or give advise. The plural form is used for all groups (thus more than one person/object), except when the subject is dual, e.g. (a pair of) eyes, legs, partners etc. The general form is used to advise people unknown to the speaker/writer, for instance in manuals or cooking books.

Infinitive

-ειн

Is used to describe the action on itself, e.g. Нιтω παнxοιн. - "I like to eat". The infinitive is actually a participle noun. (Also have a look at this post.)

Coniunctive

-e- or lengthening the root-vowel; e.g.: ἁπтω > ἁπтeω and cтω > cтαω (resp.)

Is used to state wishes, irrealities and possibilities.
