keerulisemad

Keerulisemad is the plural nominative form of the Estonian adjective keeruline in its comparative degree, meaning "more complicated" or "more intricate." It is used to compare two or more items when describing that those items are more complex than others. As a comparative adjective, keerulisemad accompanies plural nouns.

Formation and usage. The base adjective keeruline takes the comparative suffix to produce keerulisem, and the plural nominative ending -ad yields keerulisemad for describing multiple things. For example: See ülesanne on keerulisem kui eelmine, meaning "This task is more difficult than the previous one," and Need küsimused on keerulisemad kui need, meaning "Those questions are more complicated." In a broader context, keerulisemad can modify a plural subject such as "keerulisemad olukorrad" (more complicated situations).

Grammatical notes. Keeruline is an attributive adjective and agrees with the noun it modifies in number and case. The comparative form keerulisem is used for a single item, while keerulisemad is used with plural nouns. The word belongs to a common Estonian pattern where adjectives form the comparative with the suffix -em and the plural ending -ad in the nominative case. The opposite of keerulisemad is lihtsamad (simpler ones) in appropriate contexts.
