Adjectives

Types of Adjectives:
- I-adjectives: End in い (i), e.g., 高い (takai) means "tall" or "expensive."
  - Can conjugate for tense and politeness.
- Na-adjectives: Use な (na) when modifying nouns, e.g., 静かな (shizukana) means "quiet."
  - Do not conjugate but can adopt forms with です (desu) for politeness.

Modification

I-adjectives directly modify nouns, e.g., 高い山 (takai yama) for "tall mountain."
Na-adjectives utilize な: 静かな部屋 (shizukana heya) means "quiet room."

Comparative and Superlative

Comparative forms use もっと (motto) or より (yori) before the adjective.
Superlative forms use 一番 (ichiban) before the adjective.

Negation

I-adjectives negate by changing い (i) to くない (kunai).
Na-adjectives negate by adding じゃない (janai) after the adjective.

Grammar

Sentence Structure:
- Japanese typically follows a Subject-Object-Verb (SOV) order.
- Example: "私はリンゴを食べる" translates to "I apple eat."
Particles:
- Key grammatical function words define relationships between words.
- Common particles include:
  - は (wa): Marks the topic of the sentence.
  - が (ga): Marks the subject of the sentence.
  - を (o): Marks the direct object.
  - に (ni): Indicates direction or time.
  - で (de): Indicates the location where an action takes place.
Verb Conjugation:
- Japanese verbs are categorized into two groups: U-verbs and Ru-verbs.
- Verbs conjugate for different tenses: present, past, and negative forms.
- Different politeness levels are used, ranging from casual to formal.
Questions:
- Formed by adding か (ka) at the end of a statement.
- Example: "これは何ですか？" means "What is this?"

Adjectives

Types of Adjectives:
- I-adjectives:
  - End with the character い (i) and can inflect for tense and politeness.
  - Example: 高い (takai) means "high."
- Na-adjectives:
  - Require the copula だ (da) or です (desu) for predication and are less inflective than I-adjectives.
  - Example: 静か (shizuka) means "quiet."

- I-adjectives inflect for past and negative forms:
  - Past: 高かった (takakatta) means "was high."
  - Negative: 高くない (takakunai) means "not high."

- They can also act as predicates, as in その山は高い (Sono yama wa takai), meaning "That mountain is high."
