Hello Leticia!
The words "grap" and "grip" have similar meanings but are used in slightly different contexts. However, it's important to note that "grap" is not a standard English word. You might be referring to "grab" instead. So, I'll try to explain the difference between "grab" and "grip". Also don't believe me, because it can be a mistake :)
Grab: This term generally refers to quickly seizing or taking hold of something with your hand. It implies a sudden or swift action, often done hastily or urgently. For example, "She grabbed her coat as she rushed out the door."
Grip: This word refers to holding something firmly with the hand or grasping it securely. It often implies strength or a steady hold and is used in contexts where control and firmness are important. For example, "He had a firm grip on the rope during the climb."
In summary, "grab" is more about the action of quickly seizing something, while "grip" focuses on the manner of holding something securely and firmly.
