Introducing the Subjunctive.

This the Subjunctive of the Verb εἰμί and applies to most verbs except Contracts

Look for an η or ω where there would normally be a ο or ου or ε or ει

ὦ ᾖς ᾖ ὦμεν ᾖτε ὦσι

ei + e becomes eei o + o becomes oomen

The subjunctive is used to express an unfixed probable indefinite action but alsot to express encourage what some books call hortatory ad requests and proposals.
