In most cases, the prefix col- is the form taken by the Latin verbal prefix con- when it is attached to a word starting with the letter 'L'. Con- signifies "with" or "together", so, for example, "collaborate" is from con- + laborare, and means "to work together".In some cases col- is from a different source, the Latin word collum, "neck" (e.g., "collar"), or from colon, "large intestine", a borrowing from Greek "kolon".
