ok, i am now again motivated to study my complicated mothertongue. i am having trouble with , i don't understand imperfect, pluperfect, potential, potential perfect, conditional, conditional perfect. it's really frustrating trying to figure out how to make a basic verb adding the suffix for the phrase or sentence said in a standard situation like talking to someone. Ex. to say I enjoy this classroom, is  Minä iloita tämä luokkahuone. thing i don't get is which suffix goes at the end of iloita wether its -sen -set -see -mme -tte -vat? active present 1st person I enjoy would be iloitsen  active impercect 1st person I enjoyed would be iloitsin  active perfect 1st person I have enjoyed would be olen iloinnut  active pluperfect 1st person I had enjoyed would be olin iloinnut    active present 1st person conditional I would enjoy would be iloitsisin  active perfect 1st person conditional I would have enjoyed would be olisin iloinnut    active present 1st person potential I may enjoy would be iloinnen  active perfect 1st person conditional I may have enjoyed would be lienen iloinnut    Sentence I enjoy this classroom speaks in active present 1st person, so verb will be iloitsen. Then rest of words should represent target of verb, so they should be in elative tämä -> tästä and luokkahuone -> luokkahuoneesta. So sentence would be in whole (Minä) Iloitsen tästä luokkahuoneesta.    I think that going deeper into potentials and conditionals are higher level studies and firstly you should consentrate to use present active cases    Quite full pattern for walk:   http://www.cc.jyu.fi/~hetahein/tiede/verbikaava.html       wether its -sen -set -see -mme -tte -vat?   They're all active present  -sen refers to 1st person I  -set refers to 2nd person You  -see r. t. 3rd. p. (S)He  -mme r. t. 1st plural We  -tte r. t. 2nd plural You  -vat r. t. 3rd plural They
