Complex sentences: et, kui, kuigi

et — “that”: Ma arvan, et ta tuleb. kas — “whether”: Ma ei tea, kas ta tuleb.

kui — “if / when”: Kui sul on aega, tule. kuigi — “although”. sest — “because”. seepärast — “therefore”.

A comma goes before the conjunctions et, kuigi, sest and before a subordinate clause.

Word order: in the subordinate clause the verb often goes last — kui ma koju tulen. If the subordinate clause comes first, start the main clause with siis or with the verb: Kui ma koju tulen, siis ma söön / söön ma.
