- He can’t even read hiragana, let alone kanji.

彼は漢字はおろかひらがなも読めません。 meaning: He can't read kanji, let alone hiragana.

Explanation of the first grammar point ⚫︎ おろか (Orokka) is a conjunctive particle that means "not to mention," "let alone," or "far from." It indicates that something is true or not true to an even greater degree than something else. ⚫︎ It is often used with a negative verb form to emphasize the difficulty or impossibility of something. ⚫︎ Its structure is: Noun 1 + はおろか + Noun 2 + も + Verb (negative) ⚫︎ In this sentence: 漢字 (kanji) is Noun 1, ひらがな (hiragana) is Noun 2, and 読めません (yomemasen - cannot read) is the negative verb form. ⚫︎ Think of it as: "He can't do (the easier thing) *much less* the harder thing." Or in this case: "He can't read the harder thing, *much less* the easier thing." ⚫︎ Examples: ⚫︎ 私は英語はおろか、日本語も話せません。 (Watashi wa eigo wa oroka, nihongo mo hanasemasen.) - I can't speak English, let alone Japanese. ⚫︎ 彼は運転はおろか、自転車にも乗れません。 (Kare wa unten wa oroka, jitensha ni mo noremasen.) - He can't drive a car, let alone ride a bicycle.

Explanation of the second grammar point ⚫︎ The sentence follows a typical Japanese sentence structure: Subject - Topic - Object - Verb. ⚫︎ **Subject:** 彼 (kare - he) - The subject is the person the sentence is about. ⚫︎ **Topic Marker:** は (wa) - Marks the topic of the sentence. The topic is what the sentence is about. Here, the sentence is about "him". ⚫︎ **Object:** 漢字 (kanji - kanji) and ひらがな (hiragana - hiragana) ⚫︎ **Particle (Object Marker):** を (o) is implied before 漢字. Although it is omitted, we understand that it's the direct object of the verb 読む (yomu - to read). ⚫︎ **Particle (Addition/Emphasis):** も (mo) - Used after ひらがな to mean "also" or "even". It emphasizes that the subject is unable to do the action with even the easier thing, ひらがな ⚫︎ **Verb:** 読めません (yomemasen - cannot read) - This is the negative polite form of the verb 読む (yomu - to read).

Explanation of the third grammar point ⚫︎ The verb 読めません (yomemasen) is in the negative polite potential form. ⚫︎ **Potential form** indicates the ability to do something or the possibility of doing something. ⚫︎ **Verb Group 1 (u-verbs):** Change the final "u" sound to an "e" sound and add ます (masu) for polite affirmative, and ません (masen) for polite negative. ⚫︎ 読む (yomu - to read) becomes 読める (yomeru - can read) + ません (masen) = 読めません (yomemasen - cannot read). ⚫︎ Example: ⚫︎ 私は日本語が話せません。 (Watashi wa nihongo ga hanasemasen.) - I can't speak Japanese.

Explanation of the fourth grammar point ⚫︎ **は (wa):** Topic marker, indicating what the sentence is *about*. It replaces other particles like が (ga) when used. In this sentence, it marks 彼 (kare) as the topic, hence the subject is highlighted. ⚫︎ **も (mo):** Particle meaning "also" or "even." It replaces other particles like が (ga) or を (o), adding an implication of inclusion or emphasis. ⚫︎ In the given sentence, も is used with ひらがな (hiragana) to highlight that he can't read even the easier character system. ⚫︎ The combined effect of おろか and も intensifies the degree of inability, hence highlighting that he cannot read anything.

Explanation of the fifth grammar point ⚫︎ The sentence doesn't directly involve adjective conjugations. However, it's important to understand this concept in Japanese to understand grammar better. ⚫︎ **い-adjectives:** Modify nouns and conjugate by changing the final い (i) sound. For example, 高い (takai - high, expensive): ⚫︎ Negative: 高くない (takakunai - not high/expensive) ⚫︎ Polite Negative: 高くありません (takaku arimasen - is not high/expensive) ⚫︎ **な-adjectives (adjectival nouns):** Also modify nouns, but they need な (na) before the noun. For example, 静かな (shizuka na - quiet): ⚫︎ Negative: 静かじゃない (shizuka ja nai - not quiet) or 静かではありません (shizuka de wa arimasen - is not quiet) ⚫︎ Polite Negative: 静かではありません (shizuka de wa arimasen - is not quiet)
