Causal, temporal and consecutative sentences offer no special
peculiarities, being introduced by the conjunctions given in the
accidence and having the verb in the indicative mood. The particle =että=
is generally combined with the negative verb: =etten=, =ettet=, =ettei=,
etc.
Concessive sentences, introduced by =vaikka=, =vaikkapa=, _or_ =jos
kohta=, have the verb in either the indicative or the conditional. =Hän
oli niin köyhä ettei ollut mitä syödä=, _he was so poor that he had
nothing to eat_. =Vaikka näin häntä usein, kun olin Pietarissa= (_or_
=Pietarissa olessani=), =emme kuitenkaan ole tutut=, _though I often
saw him when I was at Petersburg, we were not well acquainted_. =Vaikka
hän vannoisi en sittekään uskoisi=, _though he should swear I would not
believe him_.
The first member of a conditional sentence is introduced by =jos=, or,
if negative, by =jollen=, =ellen= (=jollet=, =jollei=, etc., =ellet=,
=ellei=, etc.). The second is often introduced by =niin=. In such
sentences as _if I go, he will come_, where the realization of the
condition is considered as certain, the indicative is used—=Jos menen
niin hän tulee=. But where the realization is doubtful the conditional
present is employed, and where it is no longer possible the conditional
past. _If I were to go, he would come_, =jos menisin, niin hän tulisi=.
_If I had gone, he would have come_, =jos minä olisin mennyt, niin hän
olisi tullut=.
Final sentences are introduced by =että= _or_ =jotta=, or in the negative
form by =etten=, =ettet=, =ettei=, etc. The verb is in the conditional.
As has been described above (pp. 192 and 198) final sentences can also
be rendered by infinitives and participles. =Ilmoittakaat minulle että
minäkin tulisin ja kumartaisin häntä= (S. Matt. ii. 8), _tell me, that I
may come and worship him_. =Hän kävelee ettei vilustuisi=, _he walks that
he may not catch cold_.
