:semi: /se'mee/ or /se'mi:/ 1. n. Abbreviation for
`semicolon', when speaking. "Commands to {grind} are
prefixed by semi-semi-star" means that the prefix is `;;*',
not 1/4 of a star. 2. A prefix used with words such as
`immediately' as a qualifier. "When is the system coming up?"
"Semi-immediately." (That is, maybe not for an hour.) "We did
consider that possibility semi-seriously." See also
{infinite}.
