Second

The second (symbol: s) (abbreviated s or sec) is the base unit of time in the International System of Units (SI). It is qualitatively defined as the second division of the hour by sixty, the first division by sixty being the minute. It is quantitatively defined in terms of a certain number of periods – about 9 billion – of a certain frequency of radiation from the caesium atom: a so-called atomic clock.

Highway

A highway is any public road or other public way on land. It is used for major roads, but also includes other public roads and public tracks: It is not an equivalent term to freeway (motorway), or a translation for autobahn, autoroute, etc.

In North American and Australian English, major roads such as controlled-access highways or arterial roads are often state highways (Canada: provincial highways). Other roads may be designated "county highways" in the US and Ontario. These classifications refer to the level of government (state, provincial, county) that maintains the roadway.

In British English, "highway" is primarily a legal term. Everyday use normally implies roads, while the legal use covers any route or path with a public right of access, including footpaths etc.

The term has led to several related derived terms, including highway system, highway code, highway patrol and highwayman.

The term highway exists in distinction to "waterway".

Overview

Major highways are often named and numbered by the governments that typically develop and maintain them. Australia's Highway 1 is the longest national highway in the world at over 14,500 km or 9,000 mi and runs almost the entire way around the continent. China has the world's largest network of highways followed closely by the United States of America. Some highways, like the Pan-American Highway or the European routes, span multiple countries. Some major highway routes include ferry services, such as U.S. Route 10, which crosses Lake Michigan.

Charles

Charles is a masculine given name from the French form Charles of a Germanic name Karl. The original Anglo-Saxon was Ċearl or Ċeorl, as the name of king Cearl of Mercia, that disappeared after the Norman conquest of England.

The corresponding Old Norse form is Karl, the German form is also Karl. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as Karolus (as in Vita Karoli Magni), later also as Carolus.

Etymology

The name's etymology is a Common Germanic noun *karlaz meaning "free man", which survives in English as churl (< Old English ċeorl), which developed its deprecating sense in the Middle English period.

In the form Charles, the initial spelling ch- corresponds to the palatalization of the Latin group ca- to [tʃa] in Central Old French (Francien) and the final -s to the former subjective case (cas sujet) of masculine names in Old French like in Giles or James (< Latin -us, see Spanish/ Portuguese Carlos).

According to Julius Pokorny, the historical linguist and Indo-Europeanist, the root meaning of Karl is "old man", from Indo-European *ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain." An old man has been worn away and is now grey with age.

Child

Biologically, a child (plural: children) is a human between the stages of birth and puberty. The legal definition of child generally refers to a minor, otherwise known as a person younger than the age of majority.

Child may also describe a relationship with a parent (such as sons and daughters of any age) or, metaphorically, an authority figure, or signify group membership in a clan, tribe, or religion; it can also signify being strongly affected by a specific time, place, or circumstance, as in "a child of nature" or "a child of the Sixties".

There are many social issues that affect children, such as childhood education, bullying, child poverty, dysfunctional families, child labor, and in developing countries, hunger. Children can be raised by parents, by fosterers, guardians or partially raised in a day care center.

Legal, biological, and social definitions

The United Nations Convention on the Rights of the Child defines child as "a human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier". This is ratified by 192 of 194 member countries. In U.S. Immigration Law, a child refers to anyone who is under the age of 21.
