きっと
きっと · kitto · JLPT N4 · adverb
surely
🧰 Sounds like kit-to: with the full kit to hand, it will surely get done
Kitto sounds like kit + to. A complete kit means nothing is missing, so the result is certain. The small っ makes a clipped pause, kit-to, as firm as the confidence it expresses: surely, definitely.
