Ablative of Comparison

The ablative without a preposition can be used to express a noun that is being compared with something else.  The ablative of comparison is a replacement for comparative clauses with quam.  The ablative of comparison patterns with (and modifies) a comparative adjective (or adverb).  Here are some examples: 
bulletpuella prudentior est puero, "the girl is wiser than the boy".  Following the comparative "prudentior", "puella prudentior est quam puer" would be the equivalent using a quam comparative clause rather than the ablative of comparison
bulletQuintus diutius Athenis mansit Marco, "Quintus waited longer in Athens than Marcus."
bulletMelior est canis vivus leone mortuo, "a living dog is better than a dead lion".

The ablative of comparison can be looked at in conjunction with the ablative of degree of difference because both pattern with comparative adjectives and adverbs.  The ablative of degree of difference expresses how much more or less the subject is than the ablative of comparison:

bulletpuella multo prudentior est puero, "the girl is much more prudent than the boy"; "multo": ablative of degree of difference; "puero": ablative of comparison
