Incorrect spelling, explanation: the adjective successful has two parts: the word-formation base – success and the suffix -ful. As you can see, the root needs to be spelled with two double consonants. It’s also worth mentioning that you mustn’t change the form -ful to -full, because the other one is an independent word. The only correct version is successful, not sucessfull. Be careful not to make this mistake.

Correct spelling, explanation: the word successful is a commonly used adjective in the English language. However, it’s difficult to spell. To make things easier, you can divide the word into two parts: the root (success) and the suffix (-ful). The first one mustn’t be changed, so you have to spell it with two double consonants. The suffix -ful is used for creating adjectives. Therefore, sucessfull is not correct.
