Answer:
Well, irritable means you are like grumpy. Short tempered means you get made easily always, like a short fuse! It depends on what and why you need it. The less "harsh" term is irritable. The more harsh term is short tempered.
Step-by-step explanation:
To put it in a better view, when you are grumpy, or irritable, when you are hungry or sleepy, you get mad or frustrated quickly. But, when you are short tempered, you have trouble keeping your anger down. This is when you have a "short fuse" they like to say. Now these may look similar, but they are much different. The only common thing is you get angry, or upset real easy. The causes are much different. However, you can prevent one, irritable, by getting the right sleep, and eating a balanced meals! Sometimes you need practice or a counselor most of the time when dealing with a short temper . Not always though, friends could also help, along with family!
