carefully choosing only some things
Choosing only some people or things and saying no to the rest.
用法パターン：
selective about [something]
よくある間違い：
Learners sometimes say *"I am very select"* when they mean *"I am very selective"*. "Select" is usually a verb or a formal adjective meaning "of special quality," while "selective" describes the behavior of choosing some things and not others. Another mistake is saying *"He is a selective person"*; more natural is *"He is very selective"* or *"He is very selective about his friends."*
類義語
choosy (More informal and often slightly critical; suggests someone is hard to please.)
対義語

affecting only certain types or parts
Working on or for only one type of thing, person, or part, and not on others.
用法パターン：
a selective [drug/filter/policy] for [something]
よくある間違い：
Learners sometimes confuse this technical sense with the everyday "picky" meaning. In science and medicine, "selective" usually means *"specific to certain targets"*, not that a person or organization is being choosy. For example, a "selective drug" is one that acts mainly on one receptor type, not a medicine that someone has carefully chosen.
類義語
specific (Common in scientific and technical language; emphasizes being limited to a particular target rather than generally narrow or picky.)
対義語
nonselective (Technical term for something that affects many types or parts without distinction.)
