Explanation of the Choice of Letters in Adjective Endings

The choice of letters in adjective endings in Russian depends on the gender, number, and case of the noun they modify. Adjectives change their endings to match the gender, number, and case of the noun they describe.

For example, in the given text: - "ключев..." is an adjective in the nominative case, singular, masculine gender, and it ends with "ый" to match the masculine gender and nominative case. - "камы..." is an adjective in the nominative case, singular, neuter gender, and it ends with "ое" to match the neuter gender and nominative case. - "басист..." is an adjective in the nominative case, singular, masculine gender, and it ends with "ый" to match the masculine gender and nominative case. - "солнечные" is an adjective in the nominative case, plural, and it ends with "ые" to match the plural form. - "умч...лся" is an adjective in the nominative case, singular, masculine gender, and it ends with "лся" to match the masculine gender and nominative case. - "росист..." is an adjective in the nominative case, singular, masculine gender, and it ends with "ый" to match the masculine gender and nominative case.

The endings of the adjectives change to match the gender, number, and case of the nouns they modify.

Initial Forms of the Adjectives and Their Formation

The initial forms of the adjectives in the given text are: 1. ключевый (masculine, singular, nominative) - formed by adding "ый" to the stem "ключев-" 2. камышовое (neuter, singular, nominative) - formed by adding "ое" to the stem "камышов-" 3. басистый (masculine, singular, nominative) - formed by adding "ый" to the stem "басист-" 4. солнечные (plural, nominative) - formed by adding "ые" to the stem "солнечн-" 5. росистый (masculine, singular, nominative) - formed by adding "ый" to the stem "росист-"

The adjectives are formed by adding the appropriate endings to the stems, following the rules of Russian grammar for adjective declension.
