con-
Prefix meaning against
Con- is a prefix meaning "with" or "together," appearing in countless English words borrowed from Latin: connect, convene, conspire, congregate.
It becomes com- before b, m, and p (combine, commit, compose), col- before l (collapse, collect), and cor- before r (correlate, correct).
The prefix often intensifies rather than adding clear meaning: conflagration is just a big fire, conspicuous simply means noticeable.
