The present participle of embargo; the action of imposing a government ban on trade or movement of goods.
From embargo + the gerund suffix '-ing', which forms continuous or progressive verb forms. This suffix comes from Old English and is used to create nouns describing ongoing actions.
The '-ing' form is special because it can be used as both a verb and a noun—you can say 'They are embargoing trade' or 'The embargoing of goods took months to implement,' showing how English gerunds are incredibly flexible.
