The alphabetic principle (also: The alphabetic code)

The result is that English spelling patterns vary considerably in the degree to which they follow rules. For example, the letters ee almost always represent / iː / (e.g., meet), but the sound can also be represented by the letters e, i and y and digraphs ie, ei, or ea (e.g., sh e, sard i ne, sunn y, ch ie f, s ei ze, ea t). Similarly, the letter cluster ough represents / ʌ f / as in en ough, / oʊ / as in th ough, / uː / as in thr ough, / ɒ f / as in c ough, / aʊ / as in b ough, / ɔː / as in b ough t, and / ʌ p / as in hicc ough, while in sl ough and l ough, the pronunciation varies.
