English Vowels Don't Follow Vowel Harmony Rules

Turkish has a beautiful, predictable system where vowels in a word harmonize with each other — say a word with a back vowel, and the following suffixes typically use back vowels too. It's one of the most orderly parts of Turkish. English vowels, unfortunately, offer no such courtesy: each syllable's vowel is chosen independently, often based on old spelling patterns or historical shifts that don't follow any neat internal logic. This means you can't predict an English word's vowels from its neighbors, and unstressed vowels often just collapse into a neutral 'uh' sound regardless of what came before. Try this: take the word 'photograph' and its relative 'photography' — notice how the stressed vowel actually shifts position and quality between the two, something vowel harmony would never allow. Say both slowly, then naturally. Accepting the 'disorder' of English vowels, rather than looking for a hidden pattern, will actually make learning them faster.
