The spelling of the word "ocheltree" is a bit tricky. Its correct pronunciation is /ˈɒkəltreɪ/, which can cause confusion as the sound represented by the letter combination "ch" is not the usual "tʃ" sound but rather a guttural, Scottish "ch" sound. This is due to the word's Scottish origins. The rest of the word is fairly straightforward, with a short "o" sound followed by "k", "əl", and "tray". So when in doubt, remember the Scottish "ch" sound in the middle and you'll have the word down pat.
