IPA: /kənˈstrʌktəbl/
KK: /kənˈstrʌktəbl/
Able to be built or created using specific tools, such as a compass and straightedge, often in a mathematical context.
In geometry, a constructible number can be created using only a compass and straightedge.
Constructible → It is formed from "con-" (meaning together) and "struere" (meaning to build) and the suffix "-ible" (meaning capable of). The word "constructible" means capable of being built or constructed together.
Think of building something 'together' ('con-') and the ability to 'build' ('struere') — that's why constructible means something that can be built.
