Grammar Notes & Usage Tips
•Basic Conjugation:** As an i-adjective, 長い (ながい) follows typical i-adjective rules: for the negative form, change the ending to 長くない (ながくない), and for the past tense, use 長かった (ながかった).
•Describing Nouns:** When using 長い to describe a noun, place it directly before the noun, like in 長い髪 (ながいかみ) for "long hair." Remember, there's no need for a particle between the adjective and the noun!
•Comparisons:** For comparisons, use 長い with より (yori) to mean "longer than," such as この道はあの道より長い (このみちはあのみちよりながい), meaning "This road is longer than that road."
•Using with Verbs:** When modifying a verb, use the adverbial form by replacing the い with く, making it 長く (ながく). For example, in 長く待つ (ながくまつ), it means "wait for a long time."
