supplementary [noun]
常见错误：
Learners often confuse "supplementary" with "complementary." "Supplementary" means something extra is added, usually in quantity or detail (supplementary income, supplementary information). "Complementary" means something different that fits well together or completes something in a matching way (complementary colors, complementary skills). Another common mistake is spelling it as "suplementary" (only one "p"); the correct spelling has double "p": "supplementary."

|
supplemental (Very close in meaning; slightly more American and often used in technical, legal, or official contexts.)
