Questions & Answers about Спрятанные деньги лежат в запертом сейфе.
Why does спрятанные have a double -нн-?
It is a full-form past passive participle formed from the perfective verb спрятать (to hide). Because the verb stem ends in -а (спрята-ть), it forms the participle by adding the suffix -нн-, followed by a normal adjective ending. Here, it takes the plural ending -ые to agree with деньги.
Why is the participle запертом formed with a -т- instead of -нн-?
The word запертом (locked) comes from the verb запереть. Verbs ending in -ереть, as well as verbs ending in -нуть or those with single-syllable stems (like мыть or взять), use the suffix -т- to form their past passive participles instead of -нн-.
What case is запертом in, and why?
It is in the prepositional case. Full-form participles decline exactly like regular adjectives to match the noun they modify. Because the safe is the location (в сейфе), it is in the masculine prepositional case. The participle must match this, so it takes the masculine prepositional adjective ending -ом.
Why is the verb лежат in the plural form when the English translation says "money is"?
