Comparisons are made by using a special form of the adjective, equivalent to the English ‘-er’ or ‘more’ as in ‘bigger’, ‘more important’.
For simple adjectives where you have three different root letters, the root of the adjective is put into a particular pattern to form the comparative. Ignore all the vowels (including áyy) and you can usually identify the root letters of a simple adjective:
To form the comparative, a is added before the first root letter and between the second and third root letters:
The second and third root can be the same letter. In this case they usually (but not always) join to become a double letter in the comparative, with the stress moving to the second syllable:
If the final root letter is w or y, then this drops out altogether.
