Shanghaiing was a popular practice in the past where sailors were kidnapped and forced to work on ships. Today, it is considered illegal and inhumane. However, there are several synonyms for this word that can be used in place of the term. These include pressganging, impressing, kidnapping, and snatching. Other synonyms that can be used instead of shanghaiing include hijacking, abducting, and coercing. No matter which word you choose, the act of forcing someone to do something against their will is always wrong and should be avoided at all costs.
