An interrogative phrase used to ask about duration, length of time, or physical length. Note: 'How long' is primarily an interrogative adverbial phrase consisting of 'how' + the adjective 'long'. When used before nouns like 'time', 'period', or 'distance', it functions as a complex determiner phrase modifying those nouns. This entry focuses on its determiner-like usage with nominal complements.
