1
not physically active or moving
Not moving around or doing physical exercise, especially for a long time.
Vzorec užití:
[someone] is inactive
Častá chyba:
Learners sometimes use "lazy" when they only mean "inactive". "Lazy" criticizes someone's character, but "inactive" is more neutral and usually describes physical movement or exercise level. For example, "an inactive lifestyle" is fine, but "a lazy lifestyle" sounds more judgmental.
Synonyma
sedentary (Often used for lifestyles or jobs with a lot of sitting and very little movement.)
|
idle (Can sound more negative or critical, suggesting someone is not using their time well.)
|
motionless (Describes not moving at all at a particular moment, not a general lifestyle.)
Antonyma
active (General opposite, especially for people who move and exercise a lot.)
|
energetic (Emphasises high energy and lively movement, not just physical activity level.)

not working, operating, or in use
Not working or being used at this time, but it can work again later.
Vzorec užití:
[something] is inactive
Častá chyba:
Learners may confuse "inactive" with "broken". An "inactive" account or machine is not being used or is turned off, but it can usually work again. "Broken" means it does not work properly. Also, in computing, "inactive" is different from "deleted" or "closed": inactive things can often be reactivated.
Synonyma
idle (Often used for machines or equipment that are not running at the moment.)
|
dormant (Suggests something is sleeping or paused for a long time, like a volcano or project.)
|
unused (Focuses on the fact that something is not being used, not on whether it works.)
Antonyma
active (General opposite, for systems, accounts, or devices that are in use.)
|
operational (Stresses that something is working and ready to be used.)

not taking part or involved
Not involved in an activity or group at this time.
Vzorec užití:
[someone] is inactive in [something]
Častá chyba:
Learners sometimes use "inactive" when they mean "shy" or "introverted". "Inactive" describes behavior in a situation (not taking part), while "shy" and "introverted" describe personality. Also, "inactive" in this sense usually needs a context, e.g. "inactive in politics", not just "He is inactive."
Synonyma
uninvolved (Focuses on not being part of something or not taking part in it.)
|
passive (Suggests someone lets things happen without trying to influence them.)
Antonyma
involved (Describes someone who takes part and plays a role in an activity or group.)

Used for a disease or virus that is in the body but is not doing anything at this time.
Vzorec užití:

dormant (Common in medical and biological contexts for something that is sleeping or resting but may become active later.)
|

not chemically reactive
Not reacting, or reacting only a little, in a chemical change.
Vzorec užití:
chemically inactive [substance/gas]
Častá chyba:
Learners may confuse "inactive" with "solid" or "stable". "Inactive" in chemistry means a substance does not react, not that it is hard, safe, or unchanging in every way. A solid can be very reactive, and a stable substance can still react slowly.
Synonyma
inert (Standard technical term in chemistry for a substance that does not react easily.)
|
unreactive (General technical word for not taking part in chemical reactions.)
Antonyma
reactive (Describes substances that take part in chemical reactions easily.)
|

|
