What's "hold onto" mean? Is it different from just saying "hold?"
Answer from a Native speaker
"Hold onto" is a bit different from just "hold!" "Hold" just implies grasping something with your hands. Whereas "Hold onto," also written as "hold on to," means to grasp or clasp something tightly so that you don't let it go or let it fall. It has a stronger intention and emphasis on not letting something go. "Hold onto" can also mean to keep something for someone until they need it again. Ex: Can you hold onto my books for me until tomorrow? => to keep something for someone Ex: Can you hold this book for me quickly? => to grasp Ex: Jane held onto the rail tightly as she crossed the bridge. => to grasp and not let go
