IPA: /ˈsʌtəlɚ/
KK: /sʌtəlɚ/
Having a delicate or understated quality; not obvious or easily noticeable.
The artist's use of color was subtler than in her previous works.
Subtler → It is formed from "subtle" (from Old French *subtil*, meaning fine or delicate) and "-er" (meaning one who or that which). The word "subtler" refers to something that is more fine or delicate in nature, often in a nuanced or refined way.
Think of something that is 'more fine' or 'more delicate' — 'subtle' describes a fine quality, and '-er' indicates a comparison, making 'subtler' mean more so.
