Words Starting With "U"
Our pre-recorded sounds are fast, clear, and natural, spoken by native speakers.
Untutored
Unstütored refers to someone who has not received a formal education or guidance, often implying a lack of sophistication or refinement as a result.
Untwine
To untwine means to separate or unfold something that is twisted together, such as rope, wire, or something that is intricately connected. It can also mean to straighten out or disentangle something that has been complicated or confusing.
Untwirling
To untwirl means to unwind or release something that has been twisted or turned around, especially in a spiral or curved manner. It can also refer to the act of unwinding something, such as a rope, thread, or a spring, by rotating it in the opposite direction, reversing the twist or curl.
Untwists
to undo a twisting or twisting motion, often to straighten or uncoil something that has been twisted.
Untying
The word "untying" is the act of removing or loosening knots or bonds, often referring to the process of releasing something that is tied or bound.<br><br>Example: Can you untying the shoe laces so I can take them off?
Ununhexium
Ununhexium is a synthetic, highly radioactive, superheavy element with the atomic number 116. It is an element that is not found naturally on Earth, but can be produced in a laboratory.
Ununoctium
Ununoctium is a synthetic chemical element with the atomic number 118, and it is one of the 118 known elements. It is a noble gas and is placed in the group 18 of the periodic table. The name ununquadio is a temporary, systematic name that is used until a permanent one is officially adopted by the International Union of Pure and Applied Chemistry (IUPAC).<br><br>The element was first synthesized in 2000 by a team of scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and it was officially recognized as an element in 2016. The discovery was made by Victor Vysotsky, Yuri Oganessian, and their team, who bombarded calcium with calcium ions to produce the element.<br><br>Ununoctium is highly unstable and only exists for a short time, decaying into other elements. The half-life of ununoctium is less than 0.89 milliseconds.
Ununpentium
Ununpentium is a synthetic, highly radioactive, and extremely rare, temporary substance that exists only for a few atoms at a time. It is not a naturally occurring element and was first synthesized in 1980. It has no stable isotopes and no uses in daily life.
Ununquadium
Ununquadium, also known as Uuq, is a synthetic, radioactive, metallic element. It is a transactinide and the 14th element in the periodic table with the atomic number 114.
Ununseptium
Ununseptium is the temporary systematic name for the synthetic, highly radioactive, and highly unstable superheavy element with the atomic number 111.
Ununtrium
Ununtrium is a temporary systematic name for the synthetic, highly radioactive, synthetic element with the atomic number 113. It has no stable isotopes, and the half-lives of the most stable known isotopes, ranging from 20 milliseconds to 3 hours. Therefore, studying it experimentally in a laboratory requires preparation and use in a breeder reactor or particle accelerator.<br><br>In 2003, a research team at the RIKEN Nishina Center in Japan announced the synthesis of the element, naming it ununtrium. Its existence was confirmed by six independent experiments using different reaction mechanisms, such as fusing zinc and calcium, or calcium and cadmium.
Unusable
1. Not usable: unable to be used for any purpose.<br>2. Not productive or functioning properly.
Unused
Not used or employed; not currently in use, employment, or circulation.<br><br>Example: "The unused materials were sold at a discount."
Unusual
Exceeding the normal or expected range. Unconventional, strange, or different from what is considered typical or usual.
Unusually
Having a quality or characteristic that is not usual or expected; different from what is normal or common.
Unusualness
The quality of being unusual or not ordinary; a characteristic that deviates from what is conventional, normal, or expected.
Unutterable
Meaning: impossible to express in words; extremely difficult to describe or put into words.<br><br>Example: "The beauty of the sunset was almost unutterable, it was so breathtakingly stunning."
Unvarnished
True or straightforward in a blunt and honest way, without sugarcoating or presenting in an attractive light.
Unvarying
Unvarying means consistently the same; not changing or varying; uniform.<br><br>Example: "The unvarying sun rose every morning over the horizon."<br><br>Synonyms: constant, steady, unchanging, invariant, uniform.
Unveil
To reveal or show something that was hidden or secret, often in a surprising or dramatic way.<br><br>Example: The actor's dramatic entrance was used to unveil the plot twist of the play.
Unveiled
Somewhat hidden or concealed, but now revealed or disclosed publicly, often because it was deliberately kept secret or hidden.
Unveiling
The word "unveiling" means the act of removing a cover or a veil from something, typically to reveal its true nature or appearance. It can also refer to the act of disclosing a new development, plan, or idea to the public.
Unveils
To reveal or disclose something that was previously hidden or unknown, often in a surprising or dramatic way.
