"The father and the children go home."
Translation:पिता और बच्चे घर जाते हैं।
In Hindi, every consonant is attached to the vowel अ in its most basic form. For example, क is 'ka' not 'k'. (This अ vowel is not pronounced in certain situations like at the end of words).
Now, consider a syllable with two consonant sounds, say 'ska'. To write it in Hindi, we need to combine the letters स (sa) and क (ka) by removing the 'a' sound from the first letter. This is a 'conjunct consonant' and is usually written by attaching half of the first letter with the second, as in स्क (ska). [Note that some conjunct consonants have special forms like त्त (conjunct of त with itself), क्ष (conjunct of क and ष) and all conjuncts involving र]
So, तुम्हारा is 'tumhārā' where म्ह is 'mha'.
When you have a conjunct of a letter with itself, you stress the consonant sound. So, बच्चा is pronounced 'bachcha).
