Gr. ὑπο-, ὑπ- (f. ὑπό prep. and adv. ‘under’ = L. sub), largely employed in Greek in the formation of verbs, adjectives, and substantives.With verbs, and their derivatives, ὑπο- had the senses ‘under, beneath, down, from below; underhand, secretly; in a subordinate degree, slightly’. With adjectives and substantives, ὑπο- had the local sense ‘beneath, under’ in a prepositional relation to the substantive implied in the radical part, or the sense ‘in a lower relation, in a lower degree, slightly, somewhat, a little’ in an adverbial relation. Few Greek words containing the prefix came down through late L. and Fr. into English; the only ones of ME. age being the ecclesiastical words hypocrite and hypocrisy, found soon after 1200 (the derivatives, hypocritic, -al, etc. are later, of 16th c.). A few technical words, e.g. hyposarca, hypostasis, occur (though hardly as Eng.) in end of 14th c.; a considerable number, including hypochonder, -chondria, hypostatic, hypotenuse, hypothec, hypothesis, hypotrachelium, hypotyposis, appear in 16th c., and others, as hypocaust, hypogaster, -gastrium, hypogæal, in 17th c. But the great majority of the hypo- formations belong to the vocabulary of modern science, and have no actual Greek prototypes, but are formed (usually) on Greek elements, and more or less in accordance with Greek principles of word-formation. Hypo- has not, like hyper-, become a living element, capable of being prefixed at will to words of any origin.The first vowel in Gr. ὑπο-, L. hypo-, is short, and all the early words in English were introduced with the y short, as in hypocrite, hypocrisy, etc. The y is marked as short in all compounds with hypo- in Pronouncing Dictionaries down to the middle of the 19th c. Some later Dictionaries, while retaining short y under stress, primary or secondary, as in hypocaust, hypothetic, make it long \|aɪ\| in unaccented syllables, as in hypothesis, hypotenuse. But the later tendency in the South of England has been to treat y in all positions except before two consonants as \|aɪ\|, and, against etymology and history, to say hȳposulphate, hȳpostatical, etc.I.1. In words from Greek: the most important of these are hypochondria, hypocrisy, hypocrite, hypotenuse, hypothec, hypothesis, and their derivatives.2. In modern formations, with sense ‘under, beneath, below’, of relative position; sometimes antithetical to terms in epi- or hyper-. In one set (a) hypo- has a prepositional relation governing the n. occurring or implied in the following element, as in hypobasal, hypobranchial, hypodermic, hypoglossal; in another (b) hypo- qualifies the second element adverbially or attributively, signifying that this is itself the nether or lower of two (or more), as in hypoblast, hypomere, hypozoa (animals low in the scale).3. Mus. a. Prefixed to the names of musical modes in *hypoæolian, hypo-dorian, hypo-ionian, hypo-lydian, hypo-mixolydian, hypo-phrygian, to denote either (a) the grave modes in Ancient Greek music, beginning at a definite interval below the ordinary æolian, Dorian, etc. or (b) the ‘plagal’ modes in mediæval music, each of which has a compass a fourth below that of the corresponding ‘authentic’ mode. b. Also formerly in names of intervals measured downwards, as hypodiapason, -diapente, -diatessaron, -ditone* (see diapason, etc.). (Cf. hyper- 2.)1597Morley Introd. Mus. 98 If the leading part were highest, then would they call it [a Fuge] in hypodiatessaron, which is the fourth beneath.1651J. F[reake] Agrippa's Occ.

These words belong chiefly to pathology, and are the opposites of similar formations beginning with hyper- II.5. In Chemistry, hypo- (in contrast to hyper- 7) is used to name an oxygen compound lower in the series than that having the simple name without hypo-; thus, sulphurous acid = H₂SO₃, hyposulphurous acid = H₂SO₂, vanadic oxide V₂O₅, hypovanadic oxide V₂O₄(VO₂), vanadious oxide V₂O₃, hypovanadious oxide V₂O₂(VO).II. The more important words belonging to all these groups appear in their alphabetical order as main words; others of less importance or less frequent use follow here. (In many of these the immediate derivation is obvious, they being simply formed by prefixing hypo- to another word, the etymology of which will be found in its place: e.g. hypoazotic, f. hypo- + azotic, etc. In the following words e often replaces æ, œ, esp. in U.S. usage; the alternative spelling is not given for each word individually.)hypalgesia \|-ˈdʒiːsɪə\| Med.
