What does blebby mean?
Blebby is an adjective used to describe something marked by blebs — small, blister-like bumps or sacs filled with fluid or air. The word derives from the noun bleb, itself a term for a tiny blister, and it finds its home chiefly in technical contexts: biologists speak of blebby cell membranes fragmenting during cell death, pathologists may note blebby changes in lung tissue, and materials scientists use it for bubbles trapped in glass or flaws in coatings. Outside the laboratory, blebby serves as a vivid, informal descriptor for ordinary blistering — peeling varnish, bubbling wallpaper, or imperfect glaze. Because it names such a specific visual texture, blebby is more precise than vague terms like bumpy or lumpy, though it remains relatively uncommon in general conversation. For readers encountering it in medical reports or craft discussions, it signals the presence of those telltale little blisters rather than any other kind of irregularity.
adjectiveCovered with, containing, or characterized by blebs — small blisters or fluid- and air-filled sacs, whether on skin, tissue, paint, glass, or another surface.
- Marked or covered with small blisters or blebs, as of damaged paint, glass, or coating surfaces.
- Characterized by the presence of blebs in a biological context, such as blebs on cell membranes during apoptosis or blebs visible in lung tissue.
"The old varnish had turned blebby where moisture had seeped beneath it."
"The ceiling's blebby plaster was the first sign of the slow roof leak."
"Under the microscope, the apoptotic cells appeared distinctly blebby along their margins."
In medicine, a 'bleb' can literally be an air pocket in the lung — so 'blebby' is the rare adjective that might describe both your peeling paintwork and a chest X-ray.

Etymology of blebby
Blebby is formed straightforwardly from the noun bleb plus the adjectival suffix -y. The noun bleb itself is of uncertain ultimate origin; it emerged in English in the early modern period and is often considered imitative or expressive in character, with some lexicographers linking it to related plosive formations such as blob and bubble. Its meaning has always centered on small blisters or fluid-filled sacs, which the adjective inherits directly.
