The noun knowledge presents two problems in particular to all users of English, and one that is experienced more by those who are learning English as a foreign language.
- First, a problem with pronunciation. Although the noun knowledge is derived from the irregular verb 'to know', it is pronounced differently.
- Second, many writers are confused with the spelling.
- Although the first syllable of knowledge, in RP, rhymes with the first syllable of 'holiday' (IPA: /nɒl/) (see also Knowledge (pronunciation)), its root is know. So it is spelled with 'k-', '-n-' and '-w' round the central vowel '-o-'.
- The second syllable is written the same way as 'ledge'.
- Don't confuse the spelling of knowledge with the spelling of the rhyming word college, which is written without a '-d-'. (There is a further note, of limited use to those seeking help on 'knowledge', on one aspect of the spelling of 'college' at Collage - college.
Knowledge is one of the 117 mis-spellings listed as 'Common difficulties' in the section on 'Spelling' within 'Writing' in UEfAP.
