What does inattentive mean?
Inattentive means failing to pay close attention to what one is doing, what is happening, or what other people are saying. It often implies that an important detail, warning, or responsibility has been overlooked. The word is commonly used to describe distracted or careless behavior, such as inattentive driving, and it can also characterize a person who seems disengaged from an activity or conversation. Its tone is generally negative but not always severe: it may indicate a momentary lapse in concentration or a broader lack of care. Inattentive is related in meaning and origin to attentive, attention, and attend, but its prefix in- reverses the positive sense of attentive. It is a useful word when the focus is specifically on a failure to notice, listen, or respond, whereas careless can suggest a wider range of irresponsible conduct.

Where does inattentive come from?
Inattentive was formed in English from the prefix in-, meaning “not,” and attentive. Attentive comes through French from Latin attentus, the past participle of attendere, a verb associated with stretching toward or attending to something. The same Latin root underlies words such as attend, attention, and attentiveness.
