الگوی کاربرد:

هممعنیها
undersea (Very close in meaning; slightly more general and not as strongly technical.)
|
underwater (Broader everyday word; can refer to any water, not specifically the sea.)
متضادها

to secretly undermine or sabotage
To quietly and unfairly make someone’s plans or chances fail.
الگوی کاربرد:
to submarine [someone/something]
اشتباه رایج:

هممعنیها
sabotage (Very close meaning; more common and neutral, while "submarine" sounds more colorful and informal.)
|
undermine (Focuses on slowly weakening; less dramatic but more common than "submarine".)
متضادها
