apples

This might be a double definition.

'when i go in puts' is the first definition.

'on' acts as a link.

Can you help me to learn more?

(Other definitions for apples that I've seen before include "''The silver ... of the moon, / The golden ... of the sun'' (W B Yeats)" , "PS, leap up for the fruit" , "Loud sharp cry" , "They never fall far from the tree" , "Crisp fruits" .)
