Adjective exercises are an integral aspect of learning Estonian grammar. In Estonian, adjectives precede the noun they modify and agree with them in case, number, and gender. Through adjective exercises, students learn not only about these agreements, but also about the degrees of comparison: positive, comparative, and superlative.

Each degree has a specific structure. For instance, in the positive degree, most adjectives end in “-ne” or “-lik”, like “sinine”(blue) or “suurlik” (big). The comparative degree usually adds “-m” to the positive form, like “sinisem” (bluer) or “sügavam” (deeper), while the superlative degree is expressed by prefixing “kõige” before the comparative form, such as “kõige sinisem” (the bluest).

In addition, some adjectives can further undergo declension, which adds complexity. Exercises in this topic involve identifying adjectives in sentences, adapting them to different cases, and changing them in degrees of comparison.

Moreover, there are irregularly formed adjectives, such as “hea” (good), “parem” (better), and “parim” (best), which necessitate further distinction. By repetitively working on these adjective exercises, learners can master the use and formation of adjectives, building a strong foundation of their Estonian linguistic competence.
