Possible values:
"imperfective" (or alternatively "imperfect", "impf", "imp" or "i") – this is the default value, so it is not necessary to fill
"perfective" (or alternatively "perfect", "pf" or "p")
"pf-impf" (or alternatively "p-i" or "pi") – for verbs which can have both aspects

If the value is set to "no", it prevents the alternative version of the past participle with the -nul ending to be shown
pass
It can prevent passive to be shown or show alternative passive

Alternative passive
E. g. tisknout has two passive forms: tisknut and tištěn
