おいしい, たかい, やすい — you were already using these on Day 9. The rule underneath: in English an adjective needs a separate “is” (“the book is expensive”). Japanese い-adjectives have the “is” built in: 高い already means “is expensive,” and it attaches straight onto a noun (高い本 = an expensive book). They even change their own endings for tense — no extra verb required.
