One of the words in Russian for a plan, like the plans you have for the evening or the weekend, is план. It's a perfectly regular masculine noun, and when asking someone about their plans, it is usually used in the plural:

The answer to the question will often contain a perfective motion verb in по- to indicate where the person wants to go:

Враг is the Russian word for enemy. Try it out loud, it even sounds tough!

Правда ли, что кошка и собака враги?
Is it true that cats and dogs are enemies?

Вот видишь, они враги.
See? They are enemies.

Both Russian and English have plenty of sayings about enemies. One that comes to my mind is “Man is his own worst enemy.”

There is a similar Russian saying: Тот дурак, кто сам себе враг. How foolish it is to be your own enemy.

Peter Parker was his own enemy in Spiderman 3; the caption reads “Spider Man, the enemy in the reflection”:

A couple of plural uses for our word are:

Вам нужно прощать врагов.
You need to forgive your enemies.

Не трать своё время на врагов.
Don't waste your time on enemies.

As I was looking through pictures with the theme "enemy," I came across this old Russian poster. The slogan reads: "Our cause is just, the enemy will be broken."

There are three words that native speakers of English often confuse at first in their studies of Russian:

1. The first one of those is дома, which is an adverb that means “at home.” It never changes its endings.
2. The second is домой, which is an adverb that means “home” in the sense of “homeward/to home.” It never changes its endings.
3. The third is дом, which is a noun that means “house” or “building” and occurs in the singular and plural of all six cases. The genitive singular of this nouns is дома, which is spelled the same as #1 above, but means something different. The nominative/accusative plural is дома “houses/buildings,” which again is spelled the same as #1 above, but obviously the meanings and stress don't match.

Today we are focusing on дома in the meaning “at home.” As an adverb it cannot be used with a preposition:

Свобода is the Russian word for freedom or liberty. When my family immigrated to America over 20 years ago, it was in search of exactly that; and when we moved to New York, we got to see one of the biggest symbols dedicated to being free.

The adjectival form of свобода is свободный. It is often used in the sense of “available/free.” When you are asking whether someone is free/avaialable for consultation, you usually use the short forms of the adjective, namely свободен, свободна, свободно and свободны:

Just remember that even though the English translation for свободный is "free" it's not to be confused with бесплатно, meaning "free of charge.
