Rough, pronounced 'ruf', the 'gh' replaces the 'f' in 'fish. The fun then begins if you can work out what words the remaining bits relate to in the general English language. I had a 'doh' moment when I found out the full explanation.
gh, pronounced /f/ as in enough /ɪˈnʌf/ or tough /tʌf/; o, pronounced /ɪ/ as in women /ˈwɪmɪn/; ti, pronounced /ʃ/ as in nation /ˈneɪʃən/ or motion /ˈmoʊʃən/.
