"Sucede" is the correct spelling of the third-person singular present indicative of the Spanish verb "suceder," which means "to happen" or "to occur."
"Sucede" is also the correct spelling of the noun "sucede," which refers to a successor or heir. However, this word is less common and may be considered archaic.
Therefore, without further context, it is impossible to determine the correct spelling definitively. You must provide more information about the intended meaning and grammatical function of the word.
