Amy F has provided some very good definitions of those words for you. So I'll just give you some extra advice. Your question should have been: 'I need help' - The word 'I' is always written 'I'. Don't write 'i' - this is simply wrong - 'Help' is an uncountable noun, so you can't put 'a' before it. Either say 'I need help' or 'I need some help'. The rest of your question should read: Who can tell me what the difference is between these three words: evade, secede, escape ? Thanks in advance. Remember that capital letters at the beginning of sentences, and punctuation a the end are essential elements of the written language. These things are not fancy 'extras' - they are necessary.

Secede is a very formal word. It's used when a group formally withdraws from an organization. The best example is the American Civil War. The Southern states decided to secede from the United States and form their own country, and this is what caused the war. Evade means pretty much the same as avoid, but it's commonly used in contexts where one person (or animal) is running away. For example, "The dog evaded capture." This means that the dog avoided capture, and no one could catch it. Or, "The criminal evaded police for an hour before he was finally caught." This means that the criminal avoided the police for one hour, and then they caught him. Escape means to get free from a place where you are being held, without being given permission. For example, "The dog escaped from its cage." The dog was in a cage, and it got loose on its own. Or, "Yesterday there was a jailbreak, and 20 criminals escaped." All the criminals were in jail, and 20 of them got past the guards and out of the jail. They will need to be re-captured. I hope this helps!
