Incorrect spelling


Incorrect spelling, explanation: conscent is a mistake, probably made due to pronunciation (there is a different word, scent, which is pronounced same way as -sent in consent). The correct form is consent as the word comes from Latin consentire.

Correct spelling


Correct spelling, explanation: as many other words in English consent also comes from Latin and hence its spelling (Latin consentire). -scent ending is an incorrect form, which might occur because of the spelling of a different word – scent, pronounced same way. However conscent is not correct, and the correct form is consent.
