📝 Conjugation Notes
Always attach 「にせよ / にしろ」 to the plain (dictionary) form of verbs and i-adjectives. For na-adjectives and nouns, attach it to their plain form ending with 「だ」, or the more formal 「である」.
🔊 Pronunciation Tips
The pronunciation is straightforward: 「にせよ」 (ni-se-yo) and 「にしろ」 (ni-shi-ro). Ensure clear articulation of each mora. When used in pairs (e.g., AにせよBにせよ), there is a slight pause or breath between the two clauses.
🧠 Memory Tips
Think of 「にせよ」 as “whether it may be” (connecting to 「する」, to do, in its imperative/formal form 「せよ」). Similarly, 「にしろ」 connects to 「する」 in its informal imperative form 「しろ」. This helps reinforce the idea of “regardless of the action/state.” The core idea is “the conclusion remains the same, no matter the preceding conditions.”
