但我还是答应了英文怎么说

如果你答应了某件事，你可以用英语表达为 "I agreed to it." 或者 "I promised to do it."

这两个表达都表示你已经同意或承诺去做某事。例如：

"I agreed to help you with your homework this evening." (我答应今晚帮你做作业。)
"I promised my friend that I would meet them at the park at noon." (我答应我的朋友会在中午在公园见他们。)

"Agree" 和 "promise" 都是动词，意思是同意或承诺。 "Agree" 来自中世纪拉丁语 "ad-," 意思是 "向前" 或 "toward," 和 "gratum," 意思是 "pleasing." 因此，"agree" 的本意是 "向前走（同意），使人感到愉悦。" "Promise" 来自古法语 "promesse," 意思是 "断言" 或 "承诺." 因此，"promise" 的本意是 "做出保证" 或 "作出承诺."
