Hello Antonio, 'compulsive' relates to an irresistible urge and 'compulsory' is something required by law, obligatory, not optional. Examples: Primary education is free, and is compulsory for children of 6 to 14 years. Peter exhibits compulsive behaviours. It is challenging to live with him. I hope this helps? Beatriz

1. If something is compulsory, an outside agent compels you to do it: There is compulsory military service in some countries. 2. If something ( usually some kind of behaviour) is compulsive, the drive comes from within: He is a compulsive gambler.

Hi Antonio. "Compulsive" refers to something such as an urge or an action that is too powerful to control. When you do something compulsively, you do it against your own wishes because the desire is so strong. "Compulsory" describes something that you are required to do, such as obey the law or go to work. You have no choice in the matter when something is compulsory.
