A gate or gateway is a point of entry to a space enclosed by walls, or a moderately sized opening in a fence. Gates may prevent or control entry or exit, or they may be merely decorative. Other terms for gate include yett and port. The word derives from the old Norse "gata", meaning road or path, and originally referred to the gap in the wall or fence, rather than the barrier which closed it.

A gate may have a latch to keep it from swinging and a lock for security. Larger gates can be used for a whole building, such as a castle or fortified town, or the actual doors that block entry through the gatehouse. Today, many gate doors are opened by an automated gate operator.

Types of gates include:

This gate does not prevent entry but clearly suggests a borderline

A small but elegant gate to a meadow path

Ishtar Gate is the oldest city gate in existence

Wringin Lawang, a 14th century Majapahit split gate in Trowulan

Richly decorated Balinese temple gate

This gate at Columbia University was closed to prevent entry of protesters

Aaron Dontez Yates (born November 8, 1971), better known by his stage name Tech N9ne (pronounced "Tech Nine"), is an American rapper from Kansas City, Missouri. In 1999, Yates and Travis O'Guin founded the record label Strange Music. Throughout his career, Yates has sold over one million albums and has had his music featured in film, television, and video games. In 2009, he won the Left Field Woodie award at the mtvU Woodie Awards.

His stage name originated from the TEC-9 semi-automatic handgun, given to him by rapper Black Walt due to his fast rhyming style. Yates later applied a deeper meaning to the name, claiming that it stands for the complete technique of rhyme, with 'tech' meaning technique and 'nine' representing the number of completion.

Aaron Dontez Yates was born on November 8, 1971 in Kansas City, Missouri. He began rapping at a very early age, and would rap the letters of his name in order to remember how to spell it. He never met his father, and his mother suffered from epilepsy and lupus when he was a child, which emotionally affected him and inspired him to "search for God." He would wander around abandoned buildings with his best friend, Brian Dennis, hoping to catch a ghost on film. In 2003, Dennis was shot and killed by his girlfriend's ex-boyfriend, which further inspired Yates' search for a higher power, as well as giving him the drive to vent his frustrations in his music.
