30/05/16 Is “ASSENT” the same as “CONSENT”?

e-legal lesson

Assent and consent are mostly synonymous—they both mean to agree or to give permission—but assent connotes a greater degree of enthusiasm, and consent often comes with reluctance.

When there is doubt, consent is usually the best choice. It is much more common than assent and seems to cover a broader range of uses.
In law, these words are very close in meaning, yet there is some implication that assent is more active and enthusiastic than consent, the meaning of which sometimes slides over almost to “acquiescence”.”

What is the difference between consent and assent? 
Consent may only be given by individuals who have reached the legal age of consent (in the U.S. this is typically 18 years old).  Assent is the agreement of someone not able to give legal consent to participate in the activity.  Work with children or adults not capable of giving consent requires the consent of the parent or legal guardian and the assent of the subject.
