How do you say "Thank you" and " I miss you" in Hindi?

Question

Answer

Thank you! = धन्यवाद्! or शुक्रिया 
 " I miss you"  =  "मुझे तुम्हारी याद आती है" or  "मुझे तुम्हारी याद आ रही है"

Answer

Thank - Dhanyavaad or Shukriya
You - Tumhara or Aapka

So "thank you" means Aapka/ Tumhara Dhanyavaad/ Shukriya

I - Mein
Miss - Yaad
You - Tumhe

While translating this into Hindi we will add one more word Karoonga/ Karoongi which will show an action in future "yaad karoonga/ karoongi"

And if you are using "I miss you" in some present tense then instead of karoonga/ karoongi you will use karta hoon/ karti hoon.

Here I miss you means 
Mein tumhe yaad Karoonga (if speaker is male)/ Karoongi (If speaker is female) - If using for future.

Main tumhe yaad karta hoon (if speaker is male)/ karti hoon (if speaker is female) - If using in present tense.
