restart點解?

重新開始！

please split the word to two separate word

restart = re-start

re- = again

for example: redo = re-do = do again 再做一次

Restart means start again.
Re this word is Profix, to use before a word, means again. So you might not find any word that "re" is go before that word. So, when you saw re this word is in front of any words that means to do something again. But some word you can find in the dictionary, for example, react, responses.
