Unreferenced date January 2008 merge Athematic stem discuss Talk Athematic stem date March 2009 In Indo European linguistics , a thematic stem or vowel stem is a noun or verb stem that ends in a vowel that appears in or otherwise influences the noun or verb s inflectional paradigm . The vowel is called the thematic vowel . The noun or verb is also called thematic . In Latin , nouns of the first, second, fourth, and fifth declension s are considered thematic the first declension has the theme vowel a , the second o , the fourth u , and the fifth e . Stems with i are treated together with athematic stem s in the third declension. A similar situation appears in the Latin verb the first Latin conjugation conjugation contains vowel stems with a , the second with e , and the fourth with i . There are no Latin verbs with o or u , and there are very few Latin verbs that are athematic, which is where those verbs that are conjugated with consonant stems would be classified. Sanskrit language Sanskrit , by contrast, still preserves a large number of athematic, consonant stem verbs, while the situation in Greek language Greek is somewhere between that of Sanskrit and Latin. Most other Indo European languages have similar distinctions, or had them in their past. In the Germanic languages and the Celtic languages , the theme vowels are often hard to perceive because of the loss of final vowels. However, their presence is still felt, in a manner that defines different ways of declining nouns or conjugating verbs, so philology philologists still occasionally speak of vowel stems and consonant stems in these languages as well.

Unreferenced date September 2008 merge Thematic stem discuss Talk Athematic stem date March 2009 For other uses of the word athematic Theme disambiguation In the Indo European languages , thematic stem s are stems ending in a theme vowel a vowel sound that is always present between the stem of the word and the attached Inflection ending . Athematic stems lack a theme vowel, and attach their ending directly to the stem itself. For example, consider the endings of the Latin first declension singular nominative case Nom. rosa genitive case Gen. rosae dative case Dat. rosae accusative case Acc. rosam ablative case Abl. ros The vowel a is prominent in these case endings, so nouns like rosa came to be known as a stem nouns, with a being the theme vowel, and was later analysed as having a stem containing a root plus a Affix suffix . In fact, philology philologists now believe that the suffix in Proto Indo European language Indo European was eh sub 2 sub , with a laryngeal theory laryngeal that usually became a in the daughter languages. The distinction between thematic and athematic stems is especially apparent in the Greek language Greek verb they fall into two classes that are marked by quite different personal endings. Thematic verbs are also called verbs in Greek athematic verbs are mi verbs, after the grammatical person first person singular present tense ending that each of them uses. The entire Grammatical conjugation conjugation seems to differ quite markedly between the two sets of verbs, but the differences are really the result of the thematic vowel reacting with the verb endings in classical Greek, the present tense active endings for athematic verbs are , , , , , mi, s, si, men, te, asi n while the thematic verbs took the endings , , , , , , eis, ei, omen, ete, ousi n In Greek, athematic verbs are a closed class of inherited forms from the parent Indo European language.

Ski technique The stem technique in skiing is a method for turning the skier. It is usually credited to the Austria n Mathias Zdarsky who developed it in the 1890s. Its variations gradually replaced the telemark skiing telemark technique in Alpine skiing . The technique involves stemming the uphill ski. Stemming is pushing the tail of the ski outward skidding it across snow from a parallel position with the downhill ski to form a V shape where the tips of the skis are close together and the tails far apart. Initially the stemming ski has relatively little pressure applied much less than half the skier s weight. After the ski is stemmed, most of the skiers weight is then transferred to initiate a change in direction.

Stems can refer to two things in music, relating to music notation and production. Notation Image Parts of a note.svg right 150px thumb Parts of the note Stems are the lines which extend from the notehead. Stems may point up or down. Different facing stems indicate the voice for polyphonic music written on the same staff music staff . For single note melodies, the stems usually point down for notes on the middle line or higher, and up for those below. If the stem points up from a notehead, the stem originates from the right hand side of the note, but if it points down, it originates from the left. The exception to this rule is when a chord contains a second, in which case the stem runs between the two notes, the higher being placed on the right of the stem and the lower on the left. The length of a stem is usually that of an octave on the staff, going to either an octave higher or lower than the notehead, depending on which way the stem is pointing. Production See also List of musical works released in a stem format Stems are the individual components of a Audio mixing recorded music mix , separately saved usually to disc for the purposes of use in a remix .

Ski technique The stem Christie is a technique in skiing for turning. It is a refinement of the basic stem skiing stem technique, where prior to the turn the uphill ski is stemmed tail skidded outward from being parallel with the downhill ski to form a V shape. The turn was named after Kristiania now Oslo , Norway, where the name Kristianiasving was used for the parallel turn, differentiating it from the Telemark turn . The technique was introduced to central Europe in 1910 by the Austria n ski guide Johannes Schneider . Fact date August 2008 Along with the other two stem techniques, it formed the basis of his Arlberg technique and instruction method. The technique was popular and widely used up until the late 1960s, when its use diminished in favor of the parallel turn , inspired mostly by ski racers.
