SYZYGY, SYZYGIA, in astronomy, a term equally used for the conjunction and opposition of a planet with the sun.—The word is formed from the Greek, συζυγία, which properly signifies "conjunction." On the phenomena and circumstances of the syzygies a great part of the lunar theory depends. See ASTRONOMY, n° 220.
T, or t, the 19th letter and 15th consonant of our alphabet, the sound whereof is formed by a strong expulsion of the breath through the mouth, upon a sudden drawing back of the tongue from the fore-part of the palate, with the lips at the same time open. The proper sound of this letter is that in tan, ten, tin, tun, sat, pot, put, &c. When it comes before i, followed by a vowel, it is sounded like s, as in nation, potion, &c. When h comes after it, it has a two-fold sound; one clear and acute, as in thin, thief, &c.; the other more obtuse and obscure, as in then, there, &c.
