Common formulas:
Negations
Finnish uses negation verb which needs to be translated from many languages from negation and verb together.
=== Possession structure
Finnish does not have idiomatic verb for possession, if apertium language to translate from has vbhaver it can be translated to omistaa initially and re-organised into adessive of owner and copula on.
Adposition to case suffix
Finnish uses semantic cases for what many e.g. IE languages use adpositions:
- houses -> talot
- on houses -> taloissa
- into houses -> taloihin
etc.

The effective range of adposition to suffix mapping is a noun phrase:
- (a) green colourless dream -> vihreä väritön uni
- in (a) green colourless dream -> vihreässä värittömässä unessa
but proper noun phrase is appositive:
- for Donald Trump -> Donald Trumpille
- for president Trump -> presidentti Trumpille
in Nokia Finnish a reverse pattern is used (because computers cannot inflect variables a proxy word is inflected):
- user -> käyttäjä
- to user Joe -> käyttäjälle Joe
- file -> tiedosto
- into file thesis.doc -> tiedostoon thesis.doc
it would not be incorrect to use proper inflection in these cases.
