What does blurry mean?
Blurry is an adjective describing something that cannot be seen clearly or sharply — an image out of focus, handwriting too smeared to read, vision impaired by tears or tiredness. It also extends naturally into figurative territory: a memory can be blurry, and so can the line between two ideas or categories. The word derives from 'blur', a term with older senses of smudge and stain, and it carries no strong connotation of formality or informality; it belongs comfortably in both casual conversation and descriptive prose. Its closest synonym is 'indistinct', though 'hazy', 'fuzzy', and 'unclear' each shade the meaning slightly differently. Because modern life is full of photographs, screens, and optical devices, 'blurry' is one of those everyday words people reach for constantly without thinking — which makes knowing its precise meaning and its figurative range genuinely useful for clear writing.
Not clear or sharp in outline; difficult to see or distinguish distinctly.
"The security footage was too blurry to identify anyone."
Often used attributively before nouns: a blurry photo, a blurry line.
Vague, indistinct, or poorly defined in a non-visual sense.
"The distinction between the two roles remained blurry throughout the meeting."
Figurative use is well established but slightly less frequent than the literal sense.
Before photography gave us a word for out-of-focus images, 'blur' simply meant a smudge or stain — the camera borrowed the word and made it part of how we describe seeing itself.

Etymology of blurry
Blurry derives from 'blur', a word attested in English by the sixteenth century, originally meaning a smear or stain on a surface. Over time 'blur' broadened to cover anything indistinct, including vision and, later, out-of-focus photographs. The adjective 'blurry' was formed from this base with the common adjectival suffix '-y'; its comparative and superlative forms are blurrier and blurriest. Cognates outside English are limited, since 'blur' appears to be native to English or of uncertain Germanic origin rather than borrowed from Latin or Greek.
