What does crannying mean?
Crannying is an uncommon English verb connected with the formation of crannies — the narrow cracks or slits that appear in walls, rock faces, timber, and other surfaces. In its primary sense it describes the process by which a material splits or develops such small openings, as when frost slowly works its way into stone and leaves it crannying along old fault lines. A rarer secondary sense involves filling or packing material into crannies, as a builder might work mortar into thin gaps. The word derives from the noun 'cranny', which entered English from Old French, where 'cran' meant a notch. Because the verb has always been marginal, modern usage tends to favour plain terms like 'cracking' or 'splitting'; encountering 'crannying' today usually signals an older text, a technical trade context, or a writer deliberately reaching for precise, evocative vocabulary about weathering and decay.

"The old barn wall was crannying badly, letting draughts whistle through every gap."
"Years of frost had left the stone steps crannying along every edge."
"She spent the afternoon crannying mortar into the gaps between the bricks."
Before you say a wall is 'full of cracks', consider the almost forgotten verb behind those little gaps — crannying.
