A fellow in the broadest sense is someone who is an equal or a comrade. The term fellow is also used to describe a person, particularly by those in the upper social classes. It is most often used in an academic context: a fellow is often part of an elite group of learned people who are awarded fellowship to work together as peers in the pursuit of knowledge or practice. The fellows may include visiting professors, postdoctoral researchers and doctoral researchers.

The title of research fellow is used to denote an academic research position at a university or a similar institution.

The title of Teaching fellow is used to denote an academic teaching position at a university or similar institution.

The title fellow might be given to an academic member of staff upon retirement who continues to be affiliate to a university institution in the United Kingdom.

At Colleges of the Universities of Oxford, Cambridge, and Dublin, full fellows form the governing body of the college. They may elect a Council to handle day-to-day management. All fellows are entitled to certain privileges within their colleges, which may include dining at High Table (free of charge) and possibly the right to a room in college (free of charge).

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.
