Morphology

threatener = threaten (transparent) = threat + en + er

Standard agent nominalization from 'threaten'; although this sense emphasizes 'posing danger', the formation is regular and predictable.

Etymology

Threatener can also mean something that causes danger and comes from the same root threaten and threat, where threaten means 'to put in danger' and -er means 'one that does'. That's why a threatener can be any thing or person that is likely to harm or cause trouble.
