When using reflexive verbs with the instrumental case in Russian, it can be tricky. Here are some important tips to help you do it correctly:

1. What is a Reflexive Verb?

Reflexive verbs usually end in "-ся" (or "-сь" before a vowel).

For example, "мыться" means "to wash oneself."

2. Choosing the Right Form

When using the instrumental case with reflexive verbs, you need to pick the right form of the reflexive pronoun or noun.

For example:

• "Я горжусь своим братом." (I am proud of my brother.) – Here, "братом" is in the instrumental case.
• Mistake: Saying "Я горжусь своего братом." is wrong.

3. Using Adjectives Correctly

When you describe something about the subject with an adjective in the instrumental case, both need to match.

For example:

• Correct: "Я доволен своей работой." (I am satisfied with my work.)
• Mistake: "Я доволен своего работы." is incorrect.

4. Fixing Reflexive Pronouns

Make sure to change "себя" (myself) correctly in the instrumental case.

For example:

• "Я горжусь собой." (I am proud of myself.)
• Mistake: Saying "Я горжусь себя." is wrong.

5. Practice Sentences

Here are some sentences you can practice with:

• "Он занимается собой." (He is engaged with himself.)
• "Она довольна своей жизнью." (She is satisfied with her life.)

By following these tips, you can avoid common mistakes when using reflexive verbs with the instrumental case in Russian. Keep practicing, and happy learning!
