Latin Grammer: Comparatives
In fundis ergo aquarum est reflexio, quare maior est calor in fundo quam in superficie.
After a comparative adjective, quam becomes a coordinating conjunction that means "than." The same case or construction that precedes quam follows it. Comparisons can also be done using the Ablative of Comparison. This can be used when the first object of comparison is the nominative or accusative case.
Translate the following English sentences into Latin using a. quam and b. the ablative of comparison. (include ending punctuation)
Example:
This window is longer than those.
a. Haec fenestra est longior quam illae.
b. Haec fenestra est longior illis.
