individually
Separately, with each person or thing treated alone.
Individually means one at a time, separately, or as a single person rather than as part of a group. When your teacher asks students to work individually on a math problem, each person solves it alone instead of collaborating. When cupcakes are wrapped individually, each one has its own wrapper rather than sitting together in a box.
The word emphasizes treating or considering each person or thing as distinct and separate. A coach might meet with players individually to discuss their specific strengths and weaknesses, giving each athlete personalized attention. A scientist testing rocks might examine each specimen individually rather than making assumptions about the whole collection.
Individually often contrasts with doing something together as a group. Your class might read a book individually for homework, then discuss it together the next day. Team members might practice skills individually during the week, then combine those skills during Saturday's game. The word highlights that unique, separate attention or action given to each person or thing, one by one.
