Then you must to identify the type of comparative, there are 3.
1. Superiority (+) when we have an adjective with 2 or less syllable we only add the ending er, but it is more than 2 syllable or is a long adjective you have to write before the word more
2. Inferiority (-) This kind of comparatives are easy because you only write the word less before the adjective, you don’t have to be worry if this is short or long.
3. Equality (=) here the comparative express the same, so you are going to write as before and after the adjective.
Here are some examples:
(+) This skirt is longer that your mini skirt.
