4. Usage & nuance
- Emphasizing increase: place it right before the word to be intensified (A/V/Adv).
- Politeness: combine with 〜てください／ましょう to soften it. A direct “もっと！” can be forceful.
- “もう少し” is milder than “もっと”: もう少し = a little more; もっと = considerably more.
- With specific quantities: “もう＋[number＋unit]” (もう一杯) is common; “もっと” leans toward general degree (もっと多く).
