Ten-letter O Words Trivia Quiz

Answer: Odontology

If you wanted to study teeth, how they grow, and possible disorders associated with them and the tissues that surround them, you'd study odontology. Odontology is also involved in preventing and curing diseases in the teeth and surrounding structures.

There is a sub-field of odontology that is known as forensic odontology. Forensic odontologists help criminal cases by handling teeth found at a crime scene to identify bodies through dental records, or to determine things like age, sex, race, occupation, or socioeconomic status of the victim.

Answer: Orchestral

Orchestral music is written and performed by a traditional orchestra that is made up of a group of musicians playing brass, woodwinds, strings, and percussion instruments. Orchestral music can be heard in various venues including concert halls, movie scores, video games, and even background or theme music in podcasts and other media. Sometimes, the group that plays orchestral music is known as a philharmonic orchestra.

The word "philharmonic" comes from two Latin words - "phil" meaning love, and "harmonic" meaning music.

Answer: Overwinter

Animals that overwinter will stay in an unfavourable area despite low temperatures and unfriendly landscapes that make it difficult to find food during the winter season. Hibernation is one way to overwinter. There, animals' metabolism drops and they stay still in a sheltered area until conditions become more favourable after the winter. Plants are also forced to overwinter.

They do this in a number of different ways, including dropping leaves (e.g., deciduous trees), dying back (e.g., tulips and daffodils), or ceasing fruit production.

Some animals are also said to overwinter if conditions become very dry for the winter season, but they do not leave.

Answer: Octangular

The word "octangular" is an adjective that describes a two-dimensional shape that has eight angles. The word comes to us from the Latin word "octangulus", which derives from "octo" (eight) and "angulus" (angle).

Answer: Opaqueness

Opaqueness refers to times when light can't fully shine through something. An example might be how light is kept from shining through a window when it is frosted or steamed up. Opaqueness can also refer to something that is difficult to understand. An example might be a novel that has been translated from another language that needs constant referral to a dictionary in order to grasp the meaning of certain passages.

The word opaqueness comes to us from the Latin word "opacus", meaning "shaded or dark".

Answer: Obituaries

Obituaries are published in newspapers and online to let members of the public know of the death of a member of the community. There are generally two types of obituaries. The first is usually a simple notice in the "Births, Deaths, Marriages" section that outlines the date and time of the funeral of the deceased.

This type of obituary acts as a public death notice and may be required for some legal reasons. The second type of obituary is more of a memorial, listing life accomplishments, etc. of the deceased.

In some cases, news outlets begin working on an obituary long before a person passes away. This allows it to be posted very quickly in the event of a death of an important person. For example, the New York Times wrote the first obituary for Queen Elizabeth II when she was still heir apparent, then just updated it on a regular basis until her death over 75 years later.

Answer: Ornamental

Something that is ornamental is placed on an object to beautify the object, but does not change the function of the object. An example might be etchings on a window, engravings on a dish, or embroidery on a piece of cloth. Etymologists suggest that the word was developed in English in the 1640s from the word "ornament".

The word ornament comes from the Latin word "ornamentum", which means a decoration, enhancement or garnish.

Answer: Oscillates

"Oscillates" is a verb can describe physical things such as the pictured fan that move back and forth. It can also describe less-tangible things like feelings (e.g., "my feeling oscillates between anger and hope"). In physics, the word oscillates describes a wave or electrical current that changes in direction or strength.

The word started to be used in English in the early 1700s to describe something that moves back and forth. Etymologists have traced the word to the Latin "oscillatus" that comes from "oscillare". "Oscillare" meant to sway or wave.

Answer: Oncologist

An oncologist is a medical doctor who is involved at various stages when cancer is suspected. They will likely assist in making a diagnosis in consultation with other specialists after initial tests have been completed. After cancer has been diagnosed, an oncologist will treat the cancer with surgery, radiation, medications, or a combination.

A medical oncologist will also help to manage any side effects of treatments such as the negative side effects that are sometimes associated with chemotherapy. Oncologists stay heavily involved with treatment until they are no longer needed.

This occurs if a patient passes away, or if the cancer goes into remission. If cancer does go into remission, regular follow-ups will then be scheduled with the oncologist to ensure that the cancer does not return.

Answer: Opalescent

Something that is opalescent is an object that displays an optical phenomenon that is most frequently associated with the gem known as the opal. It can also be associated with other minerals, glass, or some liquids. The opalescent phenomenon makes light reflect from the item in such a way that the glow coming from the object changes in colour or hue as it is moved.

The changes in colour or hue are associated with reflection and refraction at different angles as the item is viewed at different angles.
