lukkoa
Lukkoa is the partitive singular form of the Finnish noun lukko, which means a lock. In Finnish, the partitive case is used in several contexts, including after negation, with verbs that indicate an indefinite amount, or when the speaker refers to the object in a non-specific way. As such, lukkoa appears in sentences where the lock is not treated as a specific, countable item in the nominative form.
In practice, lukkoa is commonly used in negated clauses and with verbs that require the partitive. Examples
Because lukko refers to a concrete, countable object, its partitive forms are frequently encountered in everyday
