a) the adjective (eg small, big)
b) the position of the adjective after the noun
c) adjectives with the male ending –i, female –it
d) degrees of adjectives (eg good, better, best)
e) The dual-plural (eg oznayimears)

Very simple: prefix to the adjective the word yoter (more) and you get the comparative (eg: better, higher, faster). The word hachi (the most) before an adjective turns it into a superlative (eg the best, highest, fastest).
