1445: shrewsbury and shropshire Nov 25, 2018
Though not always the case, it is common that English counties will just be named for their county towns' names. Often this is with adding the suffix '-shire', as with 'Oxford' to 'Oxfordshire', or 'Worcester' to 'Worcestershire'. There are exceptions, both to the suffixes and to the names totally, but in a few cases the county may still end in '-shire' but the county town is unrelated. Usually this is because of the historical county town no longer holding power, but in the case of 'Shropshire', there is not nor has there ever been a 'Shrop'. The demonym is 'Salopian' and the county town is 'Shrewsbury', but initially in Old English the county was 'Scrobbesbyrigscīr'; note that 'sc' in Old English is [ʃk] (like SHk). While 'Salop' comes from the Norman interpretation of this name too, 'Scrobbe'—which was probably a personal name—only became 'Shrews(bury)' through the sounds changing somewhat over a long time.
