Definition of a

a
Infinitive In*fin"i*tive, n. [L. infinitivus: cf. F. infinitif. See Infinite.] Unlimited; not bounded or restricted; undefined. Infinitive mood (Gram.), that form of the verb which merely names the action, and performs the office of a verbal noun. Some grammarians make two forms in English: (a) The simple form, as, speak, go, hear, before which to is commonly placed, as, to speak; to go; to hear. (b) The form of the imperfect participle, called the infinitive in -ing; as, going is as easy as standing. Note: With the auxiliary verbs may, can, must, might, could, would, and should, the simple infinitive is expressed without to; as, you may speak; they must hear, etc. The infinitive usually omits to with the verbs let, dare, do, bid, make, see, hear, need, etc.; as, let me go; you dare not tell; make him work; hear him talk, etc. Note: In Anglo-Saxon, the simple infinitive was not preceded by to (the sign of modern simple infinitive), but it had a dative form (sometimes called the gerundial infinitive) which was preceded by to, and was chiefly employed in expressing purpose. See Gerund, 2. Note: The gerundial ending (-anne) not only took the same form as the simple infinitive (-an), but it was confounded with the present participle in -ende, or -inde (later -inge).

A A ([.a] emph. [=a]). 1. [Shortened form of an. AS. [=a]n one. See One.] An adjective, commonly called the indefinite article, and signifying one or any, but less emphatically. ``At a birth'; ``In a word'; ``At a blow'. --Shak. Note: It is placed before nouns of the singular number denoting an individual object, or a quality individualized, before collective nouns, and also before plural nouns when the adjective few or the phrase great many or good many is interposed; as, a dog, a house, a man; a color; a sweetness; a hundred, a fleet, a regiment; a few persons, a great many days. It is used for an, for the sake of euphony, before words beginning with a consonant sound [for exception of certain words beginning with h, see An]; as, a table, a woman, a year, a unit, a eulogy, a ewe, a oneness, such a one, etc. Formally an was used both before vowels and consonants. 2. [Originally the preposition a (an, on).] In each; to or for each; as, ``twenty leagues a day', ``a hundred pounds a year', ``a dollar a yard', etc.

Ferment Fer"ment, n. [L. fermentum ferment (in senses 1 & 2), perh. for fervimentum, fr. fervere to be boiling hot, boil, ferment: cf. F. ferment. Cf. 1st Barm, Fervent.] 1. That which causes fermentation, as yeast, barm, or fermenting beer. Note: Ferments are of two kinds: (a) Formed or organized ferments. (b) Unorganized or structureless ferments. The latter are also called soluble or chemical ferments, and enzymes. Ferments of the first class are as a rule simple microscopic vegetable organisms, and the fermentations which they engender are due to their growth and development; as, the acetic ferment, the butyric ferment, etc. See Fermentation. Ferments of the second class, on the other hand, are chemical substances, as a rule soluble in glycerin and precipitated by alcohol. In action they are catalytic and, mainly, hydrolytic. Good examples are pepsin of the dastric juice, ptyalin of the salvia, and disease of malt.

Gastropoda Gas*trop"o*da, n. pl., [NL., fr. Gr. ?, ?, stomach + -poda.] (Zo["o]l.) One of the classes of Mollusca, of great extent. It includes most of the marine spiral shells, and the land and fresh-water snails. They generally creep by means of a flat, muscular disk, or foot, on the ventral side of the body. The head usually bears one or two pairs of tentacles. See Mollusca. [Written also Gasteropoda.] Note: The Gastropoda are divided into three subclasses; viz.: (a) The Streptoneura or Dioecia, including the Pectinibranchiata, Rhipidoglossa, Docoglossa, and Heteropoda. (b) The Euthyneura, including the Pulmonata and Opisthobranchia. (c) The Amphineura, including the Polyplacophora and Aplacophora.
A
A A (named [=a] in the English, and most commonly ["a] in other languages). The first letter of the English and of many other alphabets. The capital A of the alphabets of Middle and Western Europe, as also the small letter (a), besides the forms in Italic, black letter, etc., are all descended from the old Latin A, which was borrowed from the Greek Alpha, of the same form; and this was made from the first letter (?) of the Ph[oe]nician alphabet, the equivalent of the Hebrew Aleph, and itself from the Egyptian origin. The Aleph was a consonant letter, with a guttural breath sound that was not an element of Greek articulation; and the Greeks took it to represent their vowel Alpha with the ["a] sound, the Ph[oe]nician alphabet having no vowel symbols. This letter, in English, is used for several different vowel sounds. See Guide to pronunciation, [sect][sect] 43-74. The regular long a, as in fate, etc., is a comparatively modern sound, and has taken the place of what, till about the early part of the 17th century, was a sound of the quality of ["a] (as in far). 2. (Mus.) The name of the sixth tone in the model major scale (that in C), or the first tone of the minor scale, which is named after it the scale in A minor. The second string of the violin is tuned to the A in the treble staff. -- A sharp (A[sharp]) is the name of a musical tone intermediate between A and B. -- A flat (A[flat]) is the name of a tone intermediate between A and G. A per se (L. per se by itself), one pre["e]minent; a nonesuch. [Obs.] O fair Creseide, the flower and A per se Of Troy and Greece. --Chaucer.
