"Tautology" Meaning
A tautology is a statement or phrase that repeats itself, usually to the point of being redundant or pointless. It is a figure of speech in which a statement is made, especially in writing or speech, by using one word or phrase to repeat or echo another.
Example: "Free gift" (a gift is, by definition, something given for free). Another example is " loneliness and isolation", " at any cost" (something that is already implied by "cost"). Tautologies often occur in language as a result of redundancy, overly complex expression, or vagueness.
"Tautology" Examples
5 Examples of Tautology in English Language:
1. Free gift: The phrase "free gift" is an example of tautology as the word "free" already implies that something is given with no charge or cost.
2. Another new development: The phrase "another new" is tautological, as "new" automatically implies something is fresh or not previously existing.
3. Open secret: This phrase is an example of tautology since a secret, by definition, is not publicly known, making the term "open" redundant.
4. Random choice: Choosing something "randomly" stems from the Latin word for "by chance," so stating it's "random" again is a form of tautology.
5. Mute voice: The phrase "mute voice" is tautological since the very nature of a voice typically being silent (or possibly only audible in the form of whispers) when it is described as "mute".
Note: Tautologies often seem to add emphasis but technically convey no additional information that isn’t already implied by their individual components.

Tautologic
Tautological
A phrase or sentence is tautological when it repeats the same idea in more than one word, unnecessarily making it redundant and often humorous. <br><br>Example: "Free gift"<br><br>In this phrase, "free" and "gift" essentially mean the same thing, so it's tautological to include both words.
Tautologically
Tautologies
Tautologise
Tautologist
Tautologize
To express the same thing in two different words and yet, convey a meaning that lacks any sort of transmission of useful information, therefore making a statement unnecessary.
Tautologous
Resulting from division by itself, ie, by squaring a number that can be divided evenly by that number.
Tautomer
Tautomeric
Tautomeric refers to a type of molecules that have two or more structural formulas, which differ by the position of a functional group or isomer in a molecule. In other words, they are molecules that can exist in two or more interconvertible structural forms, called tautomers, which interconvert through a process called tautomerization.<br><br>For example, a compound may exist as either a ketone or an enol form, which are tautomers of each other.<br><br>This concept is important in organic chemistry and biochemistry, as tautomeric reactions can affect the chemical and biological properties of a molecule.
Tautomerisation
Tautomerization is a type of chemical reaction in which a molecule can exist in two or more forms, known as tautomers, that can interconvert through the movement of a group of atoms or a proton and change within the structure of the molecule, often in a reversible manner.
Tautomerise
Tautomerism
Tautomerism is a type of chemical equilibrium in which a molecule exists as two or more structural isomers that can interconvert through the movement of a group or atom, typically protons (H+). Tautomers are in a dynamic equilibrium, constantly interconverting with each other.<br><br>In other words, tautomerism is a phenomenon where a molecule can exist in two or more forms that are structurally different, but can easily convert from one to the other. This is often denoted by the prefix "tauto-" meaning "similar" or "same", and "-merism" meaning "change".<br><br>Tautomerism can occur in molecules with at least two functional groups that can rearrange to form different structures. It is commonly observed in molecules containing double bonds, acidic or basic groups, and heterocyclic compounds.
Tautomerization
Tautomerization is a chemical reaction that involves the conversion of a molecule into a structurally similar molecule, known as a tautomer, which is one of two or more isomers based on the movement of a group, typically a hydrogen atom, and a non-hydrogen atom or a functional group. This process involves the formation of a double bond, but not the movement of the double bond itself, between a particular in the molecule, leading to one tautomer having the double bond in a different part of the molecule than the other. Tautomerization has academic and practical applications in organic chemistry, including the creation of pharmaceuticals, biologically significant molecules, and the synthesis of materials.<br><br>In general, there are two types of tautomerization:<br><br>1. <strong>Enol-keto tautomerism</strong>: The conversion of a keto group (-CO) to an enol group (-CC-OH).<br>2. <strong>Enamine-imine tautomerism</strong>: The conversion of an enamine group (-CN-) to an imine group (NH).<br><br>The switching between tautomers is often influenced by the surrounding environment, such as the pH of a solution (in the case of acid or base-catalyzed reactions), pressure, or the presence of specific catalysts.
Tautomerize
To change from one isomer to another, either through the transfer of a group of atoms, or by a movement by one or more hydrogen atoms, where the latter move to a position relative to a functional group that results in a different structure.
Tautomers
In chemistry, tautomers are molecules that have isomeric structures, which differ in the arrangement of their atoms, but have different proton affinities. Essentially, they are alternatively protonated forms of a single compound.<br><br>For example, a compound that exists as a keto form (CO group) and its enol form (OC-R-H group) are tautomers. These forms are in equilibrium with each other, with the keto form generally being the more stable of the two.<br><br>Tautomers play an important role in understanding various chemical reactions and processes, especially in organic and analytical chemistry. They are also significant in biological systems, where they can influence enzyme activity, molecular recognition, and gene regulation.
