When you stand on your head instead of on your feet, this is an example of inversion.
- an inverting or being inverted
- something inverted; reversal
- a chemical change in which an optically active substance is converted into another substance having no effect, or the opposite rotatory effects, on the plane of polarization
- the conversion of an isomeric compound to its opposite
- a reversal of the normal order of words in a sentence (Ex.: “said he” for “he said”)
- the process of using an opposite rule or method
- an interchange of the terms of a ratio
- Meteorol. an atmospheric condition in which the normal properties of layers of air are reversed; esp., a temperature reversal in which a layer of warm air traps cooler air near the surface of the earth, preventing the normal rising of surface air
- the reversal of the position of the tones in an interval or chord, as by raising the lower tone by an octave
- the recurrence of a theme, fugue subject, motive, or figure in identical intervals and note values, but consistently in the opposite direction
- Phonet. a position of the tongue in which the tip is turned upward and backward
- Psychiatry homosexuality: term now seldom used
Origin of inversionClassical Latin inversio from inversus, past participle of invertere
- a. The act of inverting.b. The state of being inverted.
- An interchange of position of adjacent objects in a sequence, especially a change in normal word order, such as the placement of a verb before its subject.
- Music a. A rearrangement of tones in which the upper and lower voices of a melody are transposed, as in counterpoint.b. A rearrangement of tones in which each interval in a single melody is applied in the opposite direction.c.

- Psychology In early psychology, behavior or attitudes in an individual considered typical of the opposite sex, including sexual attraction to members of one's own sex. No longer in technical use.
- Chemistry Conversion of a substance in which the direction of optical rotation is reversed, from the dextrorotatory to the levorotatory or from the levorotatory to the dextrorotatory form.
- Meteorology An atmospheric condition in which the air temperature rises with increasing altitude, holding surface air down and preventing dispersion of pollutants.
- Genetics A chromosomal rearrangement in which a segment of the chromosome breaks off and reattaches in the reverse direction.
Origin of inversionLatin inversiō inversiōn- from inversus past participle of invertere to invert ; see invert .
Cooler surface air trapped by a layer of warm air prevents the dispersion of pollutants.
- the action of inverting
- being upside down, in an inverted state
- being in a reverse sequence, in an inverted state
- The move of one pitch in an interval up or down an octave.
- The reversal of an interval.
- The reversal of the pitch contour.
- The reversal of a pitch class succession, such as a contrapuntal line or melody.
- The subtraction of pitch classes in a set from twelve, which maps intervals onto their complements with respect to 0, and preserves interval classes, symbolized IX (X being the transposition that is inverted.).
- (genetics) a segment of DNA in the context of a chromosome that is reversed in orientation relative to a reference karyotype or genome
- (weather) An increase of air temperature with increase in altitude (the ground being colder than the surrounding air). When an inversion exists, there are no convection currents and wind speeds are below 5 knots. The atmosphere is stable and normally is considered the most favorable state for ground release of chemical agents.
- (grammar) Deviation from standard word order by putting the predicate before the subject. It takes place in questions with auxiliary verbs and in normal, affirmative clauses beginning with a negative particle, for the purpose of emphasis.
- (with an auxiliary verb) Inversion takes place in the sentence 'Is she here?' — 'is', the predicate, is before 'she', the subject.
- (for the purpose of emphasis) Inversion takes place in the sentence 'Never have I done that.' — 'have', the predicate, is before 'I', the subject, due to 'never' being the first word of the sentence.
