Learner Tips
A common mistake is to use 及び in casual conversation where と would be more natural. Remember to reserve 及び for formal writing or speech. Also, 及び connects nouns or noun phrases, not verbs or clauses.
Understanding 及び helps learners recognize formal written Japanese and use appropriate conjunctions depending on context.
