A hymn (the '-n' is silent: 'hymn' sounds like the common English personal pronoun 'him' - the two words are homophones: see also him - hymn) is a song in praise of God. It is usually intended to be sung in church, as part of a religious service: but hymns can be sung anywhere.
A hymnal - the 'n' is sounded, IPA: /'hɪm nəl/ - is a book containing the words (and sometimes the music) of hymns. A hymnal may also be referred to as a hymn book.

This is the institution set up by the universities of Hull and York in association with the National Health Service for the education of medical doctors and surgeons.
