Pronunciation

Noun

  1. A sentry or guard.
  2. a unique phrase of characters (a string), used to mark a document for processing by a computer program, also called a keyword. For example, an HTML tag such as '<table>' is a form of sentinel as its a unique phrase that is non-reaccuring in the english language. However the use of '<' and 'table' do occur in english but not in this form, so '<table>' is a relatively good sentinel phrase.
