A person or thing that cripples; something that causes severe damage, disability, or functional limitation.
From cripple + -er suffix (agent noun), creating a word for something or someone that performs the action of crippling.
A crippler is a thing that *does* something rather than a person with a condition—it's worth noticing the difference in how English creates these words, treating disability as action versus identity in different grammatical forms.
