    • t The twentieth letter and sixteenth consonant of the English alphabet. Of the Phenician alphabet the corresponding sign was the twenty-second and last; what follows t in Greek and Latin, and also in our own scheme, is the result of successive additions made to the system borrowed from Phenician. (See the several letters below.) The comparison of forms (compare A) is as follows:
    • t The value of the sign has been practically the same through the whole history of its use; it denotes the surd (or breathed) mute (or check) produced by a complete closure (with following breach or explosion) between the tip of the tongue and a point on the roof of the mouth either close behind or not far from the bases of the upper front teeth. Its corresponding sonant or voiced mute is d, and its nasal is n (see these letters). They are oftenest called dental or teeth-sounds, though the teeth have really no part in their production; hence also, and better, lingual, or front lingual, or tongue-tip, etc. They are much more common elements of our utterance than either of the other two classes, palatal (k, g, ng) or labial (p, b, m); they constitute, namely, about 18 per cent. of the sounds we make (t nearly 6 per cent., d nearly 5, n nearly 7), against palatal 4 per cent., and labial 6½. A sound which our ears would at once recognize and name as a t-sound is producible in other positions of the organs than that described above—namely, at points further back on the roof of the mouth, and with parts of the tongue behind the tip, and even of its under surface. Hence the occurrence in some languages of more than one t, distinctly recognized as separate members of the spoken alphabet (so two in Sanskrit, etc., and even four in Siamese); our own t also which forms the first part of the compound ch (= tsh) is slightly but constantly different from our t elsewhere. As in many other languages (and partly by direct inheritance from French, and even from later Latin, alterations), the t in English shows a tendency to become palatalized and converted into a sibilant when followed by palatal sounds, as i, e, y. Hence, in many situations, it combines with such sounds, either regularly or in rapid utterance, producing the ch-sound, as in question, mixture (compare the corresponding conversion of s to sh, under S); and even, in a great number of words having the endings -tion, -tious, -tial, etc., it becomes a sibilant and makes the sh-sound, as in nation, factious, partial, etc. T also, like others of our consonants, frequently occurs double, especially when medial: thus (from fit) fitted, fitter, fitting. With h, t forms the digraph th, which has the position and importance of a fully independent element in the alphabet, with a double pronunciation, surd and sonant (or breathed and voiced): surd in thin, breath; sonant in this, breathe—both as strictly unitary sounds as t and d, or s and z. They are related with t and s, etc., as tongue-tip sounds, especially with s and z as being fricative and continuable; but they are of closer position than the latter, the closest that can be made without actual stoppage of the breath, and are usually formed with the tongue thrust further forward, against or even beyond the teeth: hence their substitution for s and z by persons who lisp. In regard to their grade of closure, they are akin to f and v, and belong in one class with these (oftenest and best called spirants). As an f comes in part from an aspirated p, or ph, so also the th-sounds from an aspirated t; and in this way they have obtained their usual representation: the Greek θ, which was an aspirated t (that is, a t with separately audible h after it), was written in Latin with th, and then, when the aspirate came to be pronounced as a spirant, this was continued in use as representative of the latter. And in this case the Latin digraph has crowded out of English use the sign (or rather the two signs) which in Anglo-Saxon represented the th-sounds—namely, þ, ð—much to the detriment of our present alphabet. Of the two th-sounds, the sonant (or this and breathe sound) is much the more frequent owing chiefly to the constant recurrence of the pronominal words, particularly the, in which it is found; it is nearly 4 per cent. of our utterance, while the surd (or thin and breath sound) is less than two thirds of one per cent. In the phonetic history of the Germanic part of our language, t regularly and usually (when special causes do not prevent) comes from an older d; and, on the other hand, th from an older t: examples for t are two corresponding with duo, eat with ad or ed; for th, thou = tu, three = tri, beareth = fert; for both together, that = tad, tooth = dent.

In science:

Moreover, X = M (T h(X )) if there is some T s.t. X = M (T ), so if the operation | is definability preserving, and T ∗ T ′ = T h(M (T ) | M (T ′ )), then M (T ∗ T ′ ) = M (T ) | M (T ′ ).

In the following, we denote the solution x(t) = (xj (t)) by x(t, t) = (xj (t, t)) with xj (t) = xj (t, t) = xj (t, t ; x, ξ , θ, π), etc. if necessary.
