[i] object of comparison
The second nose is longer ¦ than the first nose.
‘than’ introduces the object of comparison i.e. the person / thing which is being compared.
Latin can form the object of comparison in two ways:
[1] comparative + quam (than) + the person / thing being compared; similar to English:
Nāsus secundus est longior quam nāsus prīmus.
[2] The object of comparison is in the ablative case without quam
Nāsus secundus est longior nāsō prīmō.
[1] and [2] have the same meaning
[ii] degree of difference
The adverb multō ‘by much’, originally an ablative of multus, is used when emphasising the amount of difference; in grammar this is known as the ablative of degree of difference i.e. by how much /the extent to which something / someone is taller, wider, richer etc.
Rēx multō fortior quam frāter est. │ The king is much / far braver than his brother.
Examples of other adverbs which function in the same way are:
[i] paulō: by a little
haec quaestiō paulō difficilior est │ this problem is a little more difficult
[ii] tantō: by so much; tantō melior / melius │ all (so much) the better
'tantō melior' inquit 'Massa, dōnō tibi cālīgās'. (Petronius) │ “Better than ever, Massa,” he said, “I will give you a pair of boots.”
[iii] dīmidiō: by half; dimidio brevius │ shorter by half; half as short
Hibernia īnsula, dīmidiō minor ut exīstimātur quam Britannia (Caesar) │ Ireland, smaller, as is reckoned, than Britain, by one half
[iv] aliquantō: by a little (somewhat); considerably
Johannes Jonstonus’s 300 page work on birds published in 1657 gives a good example of the use of aliquantō:
Masculus aliquantō longior est, corpore, collō ac cristā ampliōrī. Rōstrum fēminae brevius est … [Johannes Jonstonus: Historiae naturalis de avibus (1657)] │ The male is somewhat longer, with a larger body, neck, and crest. The female's beak is shorter …
