нему

In a sentence

• Я подошёл к нему, чтобы поздороваться.

  I approached him to say hello.

  The word 'нему' is used in the dative case to indicate the direction of movement towards a particular person, translated as 'him' in this context.

• Поэтому мы отправили письмо к нему.

  Therefore, we sent the letter to him.

  Here, 'нему' again reflects the dative case, showing the recipient of the action, specifically to whom the letter is sent.

• Мне нужно довериться ему, чтобы решить эту проблему.

  I need to trust him to solve this problem.

  Although the given sentence uses 'ему' (a related form in dative case), it represents trusting and relying on someone, here replacing 'нему' in a fitting role for the grammatical structure.
