Why do JLPT N2 learners confuse 満員 with あいかわらず?

Both words occupy adjacent semantic territory, which is exactly why the JLPT uses them as distractors for each other on multiple-choice items. The fastest way to stop confusing them is to study them as a pair, write a one-sentence contrast in your own words, and drill the pair specifically rather than each word in isolation.

Is 満員 or あいかわらず more common on JLPT N2?

Both appear in the JLPT N2 curriculum and either may show up on a given exam. Don't try to predict which one the test will choose — learn to distinguish them and you'll be safe regardless. Both belong to the General Adjectives (1) theme of N2 vocabulary.

満員 vs あいかわらず

Q: What's the difference between 満員 and あいかわらず?

満員 (まんいん) means "full house, no vacancy, sold out" and あいかわらず (あいかわらず) means "as ever, as usual, the same". Both describe a recurring social state. A learner might confuse the state of being 'full' (満員) with the fact that the crowding is 'as usual' (あいかわらず), especially when describing a daily commute.
