Ionic comes from ion as you might have guessed. An ion is a charged particle (either positive or negative), and ionic is the adjective meaning charged.

'Ionic molecule' is an oxymoron, though some things (acid salts, for example) are usually called 'molecules' since they have a definite size and consist mostly of covalent bonds, even though they have at least one ionic bond and are thus not technically molecules.
