“How do verb conjugations work in Japanese?”
Japanese verbs conjugate based on tense, politeness, and mood. For example, the polite present form adds ‑ます to the verb stem, while the past tense uses ‑ました. Unlike English, Japanese verbs don't change based on the subject — the same form works for "I", "you", and "they".
