IPA: /kənˈtræktəbl/
KK: /kənˈtræktəbl/
Able to be made smaller or reduced in size.
The muscle is contractible, allowing it to become shorter during movement.
Contractible → It is formed from "con-" (meaning together) and "tractus" (meaning drawn or pulled) and the suffix "-ible" (meaning capable of). The word "contractible" means capable of being drawn together or reduced in size.
Think of something that can be 'drawn together' ('tractus') — that's why contractible means it can be made smaller or reduced.
