> Pitara (S) <--> Father (E) <--> Vater (G)

> Matara (S) <--> Mother (E) <--> Mutter (G)

> Bhratara (S) <--> Brother (E) <--> Bruder (G)

> Duhitar (S) <--> Daughter (E) <--> Tochter (G

Since you seem to be quoting the Sanskrit words in their root forms, (to which the case-lacking English and German equivalents most closely correspond) your spellings are incorrect. The correct forms are:

pitr

mātr

bhrātr

duhitr

No thematic 'a' on the end.

You might be confusing it with the nominative plural case forms:

pitarah

mātarah

bhrātarah

duhitarah

Thanks for the info, that makes the words even more similar to each other across three main languages of Indo-European family.
