"Here is our plan."

Translation: Вот наш план.

[RobHicks2]

When do I use наш instead of наше?

[JanisaChatte]

"Наш" is "our" for masculine nouns.

"Наше" is "our" for neuter nouns.

[ensignandy18]

How can I tell the difference between what is a masculine noun, a neuter noun, or a feminine noun?

[Greyson860442]

Look at the ending of the noun. If a noun ends with a consonant, it is masculine. Female end in a, neuter in o. There are instances where Female and Neuter nouns end with other vowels, but think of this as a rule of thumb to begin identifying gender.

[diogo8484]

JaniseChatte, and how about feminine and plural nouns?

[JanisaChatte]

"Наша" for feminine nouns and "наши" for plural nouns.

[Oberoth-SGA]

There is a different meaning of the word план in Russian. It means - marijuana. Of course this is slang. So if You put on a table a matchbox and said "Here's our plan" someone can think about marijuana.

[David843194]

In a previous lesson "наше план" was used, not "наш". Why?

[linag17]

Why is this здесь not an acceptable substitute?

[JanisaChatte]

Because in this sentence you're presenting the plan, so you must use "вот", which translates to "here is".

[fatasskell]

Is it the same explanation foe "тут" ?

[mightypotatoe]

Yes, тут wouldn't work in this sentence for the same reason as здесь.
