=-sto=, generally used of inanimate objects; =kirjasto=, _a library_;
=laivasto=, _a fleet_; =hongisto=, _pinewood_.
=-uee= (original form =uehe=, nominative =-ueʻ=), generally used of
animate objects; =matkue=, =laivue=, =seurue=.
III. Names of abstract qualities are formed from adjectives with the
suffix =-ute=, =-yte= (nominative =-us=, =-ys=). Before this suffix =a=,
=ä=, =e= are changed to =u= or =y=, and form a long vowel; =hyvyys=,
_virtue_ (=hyvä=); =rakkaus= (from stem =rakkaa=); =arkuus=, _cowardice_;
=turhuus=, _vanity_. If a root ends in =i= or =ii= this vowel generally
becomes =e= in dissyllabic roots, and =u= in polysyllabic. =Kalleus=, but
=naapuruus=, =kumppanuus=.
