I used בביתה here and was marked wrong. What is the usage of הביתה? I thought it was just 'home'. Can it not be used with prepositions?
The word "הביתה" is equivalent to "לבית שלי", and it's mostly used in phrases like הלכתי הביתה, חזרתי הביתה (i went home, i came back home), etc.
I thought הביתה was equivalent to לַַבית, without a possesive שלי...
