Lesson 5
Judgment & Certainty
- 1 〜に違いない ~ni chigai nai must be / I'm sure Seeing the evidence and concluding, with confidence, that it must be so.
- 2 〜ような気がする ~you na ki ga suru I have a feeling that No real evidence, just a hunch — the way to voice an uncertain feeling.
- 3 〜っぽい ~ppoi -ish / tends to "Childish", "forgetful" — how something looks, or the habit someone has.
- 4 〜ふりをする ~furi o suru pretend to Not actually so, but acting as if — the "pretend" pattern.
- 5 まるで〜ようだ marude ~you da just like "Just like…!" — a comparison you both know isn't literally true.

「事務所の電気がついている。課長はまだいる＿。」 — which says 'he must still be there'?
💡 Hint:A confident guess from evidence.
〜に違いない = 'must be' — a firm guess from evidence. ような気がする is only 'I have a feeling', not sure.
「はっきり覚えていないけど、前にもここに来た＿。」 — fill the blank.
💡 Hint:Not certain, just a feeling.
〜ような気がする = 'I have a feeling' (a hazy memory). 来たふりをした means 'pretended to have come', and まるで can't sit here.
「私は忘れ＿から、いつもメモをする。」 — fill the blank.
💡 Hint:A habit — something that keeps happening.
Vます＋っぽい = 'prone to ~' (忘れっぽい). The other three can't attach to the bare stem 忘れ.
「本当は分からないのに、先生の前で分かった＿。」 — fill the blank.
💡 Hint:Feeling one thing, showing another.
〜ふりをする = 'pretend to ~'. 分かったに違いない ('surely understood') clashes with のに, and 分かったのようだ is ungrammatical.
「今日は暖かくて、まるで春の＿。」 — fill the blank.
💡 Hint:The ending that pairs with まるで.
まるで N のようだ = 'just like ~'. 春のっぽい and 春のに違いない break on the の, and ふりをする makes no sense here.
「その服、ちょっと子ども＿ね。」 (it looks a bit childish) — fill the blank.
💡 Hint:Noun + '-ish'.
N＋っぽい = '-ish' (子どもっぽい). ような気がする needs の after a noun, and に違いない would say 'it's definitely a child'.
Which is unnatural?
💡 Hint:What goes between a noun and ようだ?
N＋ようだ needs の in between: 夏のようだ. みたいだ and っぽい attach straight to the noun.
「あの店はいつも人が並んでいる。きっとおいしい＿。」 — fill the blank.
💡 Hint:A confident guess to match きっと.
きっと〜に違いない = 'it must be ~'. おいしいのようだ is wrong (no の after an い-adjective), and ふりをしている would mean the shop is pretending.
