كف بالانجليزي

the part of the body at the end of the arm, including the fingers and the thumb

صَفَعْتُ وَجْهَهُ بِكَفِّيَ الأَيْمَنَ

I slapped his face with my right hand

أَمْسَكَتِ الكُرَةَ بِكَفٍّ وَاحِدٍ

She caught the ball in one hand

to fold the edge of a piece of clothing over and over to make it shorter

كَفَّتْ أَكْمَامَهَا لِتُبْدِيَ أَسَاوِرَهَا الذَّهَبِيَّةَ

She rolls up her sleeves to show her gold bracelets

كَفَّ الصَّغِيْرُ بِنْطَالَهُ فَوْقَ رُكْبَتَيْهِ أَثْنَاءَ لَعِبِهِ الكُرَةَ

The little kid rolled his pants over his knees while playing football
