hemi, semi & demi



These ROOT-WORDS are Prefixes HEMI, DEMI & SEMI meaning HALF. However, there is a difference in the interpretation which each one has of the word. When we say HEMIsphere we don’t really mean half of the sphere, we mean one side, right side or left side. When we say DEMI we mean less or not quite, as DEMImillionaire. When we say SEMI we mean partly, as SEMI civilized & SEMI barbarous. There is an amusing combination of the three in music - hemisemidemiquavers, short notes sung in trills.
