omata

1. (proscribed, transitive) to have

• Although omata is an acceptable word, it is regarded as artificial by many, and the language instructors tend to discourage its use. The standard way of expressing possession in Finnish is to use olla with the possessor in the adessive case. Depending on the context, verbs like osata (“to be able, to know”), tarvita (“to need”) and saada (“to get”) may work even better:

  Maalivahdin on tärkeää omata nopeat refleksit.
  → Maalivahdilla on tärkeää olla nopeat refleksit.
  → Maalivahti tarvitsee nopeat refleksit.

  It's important that the goalkeeper have quick reflexes.

  Riitta omaa hyvät tiedot biologiasta.
  → Riitalla on hyvät tiedot biologiasta.

  Riitta has good knowledge of biology.

A good writer is supposed to reserve the use of omata to situations where it actually simplifies the sentence, which may be the case with participle structures :

Stoalaiset katsoivat, että ihmiselle on tärkeää, että hänellä on luonnonmukainen tahto.
~ Stoalaiset katsoivat, että ihmiselle on tärkeää omata luonnonmukainen tahto.

The stoics opined that it's important for a man to have a natural will.
