Por ke = In order that, so that, to the end that. Por ke is always followed by the Imperative mood, because, when used, this expression implies order (see remarks on Imperative, par. [201]).
Examples.—Por ke mi rekompencu vin, konvenas, ke vi ĝin meritu = In order that I may recompense you, it is proper (fitting) that you merit it. Mi volas ĉion fari, por ke vi estu kontenta je mi = I wish to do everything, so that you may be satisfied with me, or, I will do everything to please you.
Post kiam = After.
Example.—Post kiam la suno subiris, ni revenis hejmen = After the sun set we returned home.
Same kiel = As, just as (par. [112]).
Example.—Same kiel la patrino amas sian infanon, tiel mi amas vin = Just as the mother loves her child, so do I love you.
Se = If.
Example.—Mi ĝin faros, se mi povos = I shall do it if I can (shall be able).
Se ne = If not, otherwise, lest.
Example.—Lernu vian lecionon, se ne, mi vin vergos! = Learn your lesson, otherwise I shall cane you!
