What does distractibility mean?
Distractibility is the noun form of 'distractable' (also spelled 'distractible') and refers to the degree to which a person is easily diverted from what they are doing by external sights, sounds, or internal wandering thoughts. Someone with high distractibility struggles to maintain focus, while someone with low distractibility can concentrate steadily despite interruptions. The word appears most often in psychology, psychiatry, education, and workplace writing: it is a recognized symptom dimension of ADHD, a factor in cognitive assessments, and a frequent topic in discussions of modern digital life, where notifications and open-plan offices are blamed for eroding attention. Its connotations are largely negative when describing performance, though the word itself is clinical rather than insulting. Because it names a trait rather than an act — unlike 'distraction,' which denotes the interrupting thing itself — distractibility is useful precisely for discussing attention as a stable characteristic of a person or situation rather than a single lapse.
nounThe quality or tendency of being easily distracted; an inability to sustain attention on one thing for long because attention is repeatedly drawn elsewhere.
- The tendency to be easily diverted from a task or object of attention by irrelevant stimuli.
- (In psychology and medicine) A measurable trait or symptom involving impaired sustained attention, notably in ADHD.
"The teacher noticed that his distractibility improved markedly once he began sitting near the front of the classroom."
"Her distractibility during long meetings was legendary — even a passing pigeon could derail her train of thought."
"The clinician recorded elevated scores for distractibility on the child's behavioral assessment."
Distractibility is an uncountable abstract noun and does not take a plural form.
"His distractibility became apparent during the three-hour lecture."
Distractibility isn't just rudeness — psychologists measure it on standardized rating scales, and it's one of the core diagnostic markers of ADHD.

Etymology of distractibility
Distractibility derives from the Latin verb distrahere ('to pull apart, draw away'), formed from dis- ('apart') plus trahere ('to drag, pull'). English borrowed 'distract' in the late Middle Ages via Latin, and the adjective 'distractible' arose later, with 'distractibility' formed from it using the Latinate suffix '-ity' that turns adjectives into abstract nouns. The same root gives us 'attract,' 'contract,' 'extract,' and 'traction,' all built on trahere's sense of pulling.
