Conjunctions are the most wieldy of the words. Their ability to enhance, extend, change, transform, and explain the meaning eases the effort of communication. Advanced or sensitive or intuitive users find that elision of the conjunction increases effect. One phrase follows another as obviously as January follows December and February follows January, without recourse to the implied but or nevertheless or so. The return to work after Christmas-New Year follows logically. The noise on first day of school is loud and bright. Necessity, though, enforces use of a because or an and or a therefore in the majority of communication.
