Words concluding with a pair of identical letters are a common feature of English orthography. Examples include “tall,” “spill,” and “fuzz.” This characteristic frequently arises due to suffixation (adding -ed, -ing, etc.) or stems from the word’s etymological roots.
Understanding this orthographic element enhances reading and spelling proficiency. It provides a visual cue for pronunciation, particularly for younger learners. Historically, the doubling of final consonants often reflected changes in vowel sounds in Middle English. This knowledge can offer valuable insights into the evolution of the language and the interconnectedness of spelling and pronunciation across time.
