Correct spelling

incident

Correct spelling, explanation: incident, like many English words, has its roots in Latin, specifically in a word incidere, therefore the spelling remained relatively unchanged. When contemplating the spelling of similar words of Latin origin, it is worth to remember that the original consonants rarely change, which is also the case in incident.

Incorrect spelling

insident

Incorrect spelling, explanation: incident comes from Latin incidere, which explains its spelling. In case of insident, the spelling may look convincing as it fits the pronunciation quite well, but in this case c is also read as s. So it may be tricky, but insident is definitely not a correct word.
