The word "knotberry" is spelled with a "k" instead of a "n" because it comes from the Old English word "cnotta," which was pronounced with a "k" sound. It is phonetically transcribed as /ˈnɒtbɛri/. The "o" is pronounced as a short vowel, the "t" is followed by the "b" sound, and the stress is on the second syllable. The berry itself is a type of fruit that grows on a shrub or small tree, similar to a raspberry, but with a tart flavor.
