in-

A kissing cousin to the prefix ir-, this prefix's meaning varies by context and the word it is attached to. Its secondary usage is a reinforcement, thus how irregardless is a strong form of regardless, and inflammable can mean both extra-flammable and not-flammable.

So, of course, it's funny to apply the archaic meaning to the Dodge Intrepid.

In- (?). [See In, prep. Cf. Em-, En-.]

A prefix from Eng. prep. in, also from Lat. prep. in, meaning in, into, on, among; as, inbred, inborn, inroad; incline, inject, intrude. In words from the Latin, in- regularly becomes il- before l, ir- before r, and im- before a labial; as, illusion, irruption, imblue, immigrate, impart. In- is sometimes used with an simple intensive force.
