(_a_) _Copulative_—=ja=, =ynnä=, and =sekä=, _also_; =sekä ... että=,
_both ... and_; =ka=, =kä= (enclitic), _and_.
(_b_) _Disjunctive_—=eli=, =tahi=, =tai=, =taikka=, _or_; =joko ... tai=,
_either ... or_.
(_c_) _Adversative_—=mutta=, =vaan=, _but_; =kuitenkin=, =toki=,
_however_.
(_d_) _Inferential_—=sentähden=, =siksi=, _therefore_; =siis=,
=niin-muodoin=, _consequently_; =niin=, _so, accordingly_.
(_e_) _Causal_—=sillä=, _for_; =kun=, =koska=, _because_.
(_f_) _Comparative_—=kuin=, _than_; =ikäänkuin=, _as, if_.
(_g_) _Temporal_—=kun=, _when_; =jahka=, =heti kuin=, _as soon as_;
=ennenkuin=, _before that_; =sittenkuin=, _after that_.
(_h_) _Final_ and _Consecutive_—=että=, =jotta=, _that_.
(_i_) _Conditional_—=jos=, _if_.
(_j_) _Concessive_—=vaikka=, =jos=, =kohta=, _even if_.
(_k_) _Interrogative_—=ko=, =kö= (enclitic), =tokko=, =josko=, =vai=, _is
it ... or_ (like the Latin ‘utrum’ ... ‘an’).
It will be noticed that these conjunctions are in great part merely cases
of pronouns or adjectives, e.g. =sentähden=, =kuin=, =sillä=. =Ynnä=
appears to be a contracted essive from =yksi=; and =ja= and =toki= to be
borrowed words.
