between
between the devil and the deep blue sea: seedevil.
between a rock and a hard place: seerock.
between you and me in confidence; confidentially.
☞ The alternative version between you and I is often used, but it is frowned on by sticklers for correct usage (me is the form of the pronoun that follows a preposition). A further alternative that avoids the problem is between ourselves. An informal extended version is between you, me, and the gatepost.
few and far between: seefew.
