Old English word "speech, talk, utterance, word," from Proto-Germanic *wurdan (cf. Old Saxon, Old Frisian word, Dutch woord, Old High German, German wort, Old Norse orð, Gothic waurd), from PIE *were- "speak, say" (see verb).
The meaning "promise" was in Old English, as was the theological sense. In the plural, the meaning "verbal altercation" (as in to have words with someone) dates from mid-15c. Word processor first recorded 1973; word processing is from 1984; word wrap is from 1977. A word to the wise is from Latin phrase verbum sapienti satis est "a word to the wise is enough." Word of mouth is recorded from 1550s.
It is dangerous to leave written that which is badly written. A chance word, upon paper, may destroy the world. Watch carefully and erase, while the power is still yours, I say to myself, for all that is put down, once it escapes, may rot its way into a thousand minds, the corn become a black smut, and all libraries, of necessity, be burned to the ground as a consequence. [William Carlos Williams, "Paterson"]
(Gr. Logos), one of the titles of our Lord, found only in the writings of John (John 1:1-14; 1 John 1:1; Rev. 19:13). As such, Christ is the revealer of God. His office is to make God known. "No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him" (John 1:18). This title designates the divine nature of Christ. As the Word, he "was in the beginning" and "became flesh." "The Word was with God " and "was God," and was the Creator of all things (comp. Ps.33: 6; 107:20; 119:89; 147:18; Isa. 40:8).
