What are some common Japanese grammatical mistakes made by learners

Some common Japanese grammatical mistakes made by learners include:

• Incorrect usage of particles, which are crucial in marking grammatical relationships in Japanese sentences. Errors in particle choice often lead to misunderstandings of meaning.
• Problems with verb conjugations and tense usage, as Japanese verbs change form based on tense, mood, and politeness level.
• Mistakes with aspectual forms, reflecting actions’ completion or continuity, which can differ significantly from learners’ native languages.
• Errors in polite and honorific speech (keigo), which involves complex verb forms and vocabulary tied to social hierarchy—a difficult area for learners.
• Misuse or omission of sentence-ending particles that express the speaker’s emotional nuance or questions.
• Difficulty in correctly using compound verbs (fukugoudoushi), which are combinations of two or more verbs with native syntactic rules.
• Incorrect adjective conjugations, especially distinguishing between i-adjectives and na-adjectives.
• Problems understanding and applying appropriate word order since Japanese syntax can differ from many learners’ mother tongues.

These errors are often influenced by learners’ native language interference and the complexity of Japanese grammar, such as its system of particles, verb forms, and politeness levels. ^{8, 13, 18, 19}
