📝 Conjugation Notes
Always attach 「に際して」 to the dictionary form of a verb or directly to a noun. There are no other conjugations for this grammar pattern itself.
🔊 Pronunciation Tips
「に際して」 is pronounced “ni saishite.” Pay attention to the long vowel sound in 「さい」 (sai). The “i” in “ni” is often slightly devoiced or barely pronounced in rapid speech, but for clear articulation, pronounce it distinctly.
🧠 Memory Tips
Think of 「際 (sai)」 as meaning “occasion” or “juncture.” So, 「に際して」 literally means “at/on the occasion/juncture.” This helps remember its usage for specific, important moments.
