seasoned

Compared meaning: very experienced and skilled (adjective).

比较义项：经验丰富的，老练的（形容词）。

• veteran

  Stresses long years of service or seniority in a role, often implying age; also very commonly used as a noun (a veteran).

  强调在某个职位上任职多年、资历深，常暗含年长；也非常常作名词使用（a veteran，意为“老兵、资深人士”）。

  The veteran officer trained new recruits after twenty-five years of service.

  这位资深军官在服役二十五年后训练新兵。

• seasoned 本词

  Emphasizes skill and confidence gained through practice, without implying old age; pairs naturally with professionals like a seasoned traveler or seasoned chef.

  强调通过反复实践获得的技巧和自信，并不暗示年纪大；常与职业搭配，如seasoned traveler（经验丰富的旅行者）或seasoned chef（老练的厨师）。

  Despite being only twenty-five, she was already a seasoned negotiator.

  尽管只有二十五岁，她已经是一位老练的谈判专家了。

Veteran and seasoned both describe someone very experienced. Veteran stresses long years of service and often implies an older person; its sense 'old soldier' is not compared. Seasoned stresses skill gained through practice, without implying age; its sense 'flavored or dried food' is not compared.

veteran和seasoned在这个义项上都形容“经验丰富、老练”，语境相近，容易混淆；但veteran更强调资历和任职年限，常隐含年长；seasoned更强调通过实践获得的技巧和熟练度，不一定与年龄有关。这里不比较veteran作名词表示“老兵”，也不比较seasoned作形容词表示“调味的/风干的”的用法。
