The word 'weblog' is a modern compound, a portmanteau of 'web' and 'log'. 'Web' evolved from the Old English term for woven cloth, a metaphor perfectly suited for the interconnected network of the internet. 'Log' originates from the maritime practice of recording a ship's speed and progress using a wooden float, which generalized to mean any chronological record. Fused in the late 1990s, 'weblog' literally means "a record kept on the web," capturing the essence of an online journal or diary. Its rapid truncation to the simpler 'blog' exemplifies the tendency of language to streamline new, frequently used terms.
