Why do JLPT N1 learners confuse 終始 with 病?

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 終始 or 病 more common on JLPT N1?

Both appear in the JLPT N1 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 Nouns (8) theme of N1 vocabulary.

終始 vs 病

Q: What's the difference between 終始 and 病?

終始 (しゅうし) means "beginning and end; from beginning to end; doing a thing from beginning to end" and 病 (やまい) means "illness; disease". 終 uses the thread radical (糸), while 病 uses the sickness radical (疒). These radicals are often confused by beginners because they both provide significant visual weight to the left and top-left of the kanji.

Why JLPT N1 learners mix up 終始 (しゅうし, “beginning and end; from beginning to end; doing a thing from beginning to end”) and 病 (やまい, “illness; disease”).
