"Pear-shaped" as an idiom in British English means that something has gone completely and comprehensively wrong — nothing to do with the shape of a pear. The origin is disputed (possibly from RAF slang, possibly from pottery), but the figurative meaning is firmly established. To say a plan "went pear-shaped" is to say it failed badly. Learners who know only the literal meaning will completely misread sentences using this idiom.
"V-shaped" and "U-shaped" in economic and political analysis describe the trajectory of decline and recovery. A V-shaped recovery falls sharply and then rises sharply; a U-shaped recovery has a longer period at the bottom. These have become standard analytical vocabulary in journalism, political debate, and policy discussion — not just descriptions of graphs but predictions about how events will unfold.
A trick to remember it
"Shaped" = shaped like, completely literal and productive: attach it to almost any object (heart-SHAPED). The one trap: "go pear-shaped" is a fixed idiom (to go badly wrong), unrelated to the real shape of a pear.
