"The boys eat bread."
अनुवाद:लड़के ब्रेड खाते हैं।
It is the button at the top center (्) After typing ब use that button.
ब makes the sound ba (a should be a schwa) and br makes the sound br.
Also instead of र in लरके, you want to use ड़ to make लड़के.
Lastly खाना when used as a verb is the infinitive form - (to eat). The right conjugation to go with लड़के as the subject is खाते हैं.
