Learn Russian: Почему мы нигде не видим ваше расписание? - Why do we not see your schedule anywhere?

In English, double negatives usually cancel each other out, but in Russian, they are required! Whenever you use a negative word like нигде (nowhere / not anywhere), ничего (nothing), or никогда (never), you must also put не (not) directly in front of the verb. Literally, the sentence translates to "Why do we nowhere not see..."

Why does the verb видим have an -им ending? Doesn't the dictionary form видеть end in -еть?

Yes, видеть ends in -еть, so you might expect it to follow the first conjugation pattern and become видем. However, видеть is one of a few important exception verbs. It follows the second conjugation pattern (just like most verbs ending in -ить), which is why we get мы видим (we see), ты видишь (you see), and so on.

The word расписание (schedule) is the direct object here. Why didn't its ending change?

Because расписание is a neuter noun. Neuter nouns (which typically end in -о, -е, or -ие) and inanimate masculine nouns do not change their endings in the accusative case (the case used for direct objects). Because the noun doesn't change, the possessive pronoun ваше (your) also stays exactly as it looks in the dictionary.

Does нигде have to come right before не видим?
