The prefix that commits to almost, then refuses to follow through.
means A versatile shorthand meaning half or partial, also slang for a large tractor-trailer truck or a semifinal.
from From Latin semi-, meaning half, the older cousin of Greek hemi-; the truck sense comes from semi-trailer, which rests half on the cab.
Trailer truthA semi-trailer has no front wheels; the cab carries it.
Not quite halfSemi often means partial, not literally fifty percent.
Music shrinkageA semibreve is a whole note despite the name.
