Translation:The animals are beautiful, we are watching them.
"To look at" means "להסתכל על". For example: "הסתכל על העץ הזה!" means "look at this tree!"
Watching usually means looking at something for a period of time and see how it changes. For example: "צפיתם בתכנית?" means "did you watch the show?"
Yes. Ever see people baby talking to their pets? Even Oprah (gag) called her dog the most handsome dog in America... (I just searched handsome dog,... seriously... ).
According to tips and notes, the form of them as a suffix with these prepositions is -ן, and the form of ב does not change, then, what am I missing when I see בהן? Thank you.
